Current Mode based Communication System
Prof. Dr. Uday Pandit Khot, N.A. Bhagat
DOI: 10.17148/IJIREEICE.2015.3301
Abstract: This paper focuses on the various advantages of current mode circuits over the widely used voltage mode circuits in communication system. The individual blocks of a basic communication system are designed in voltage mode and the circuits are then converted into their equivalent voltage mode. Conclusions are drawn based on the various responses observed in both the modes. The existing available VM devices/circuits for communication systems are having restricted band width, and size constraints. Using such devices, the supply voltage level cannot go below minimum value (as low as 1.2 volts) and also there is problem of power dissipation due to size constraints. The size cannot be further reduced as the power dissipation problem may damage the device. As compared to VM building blocks, the current mode (CM) building blocks can generally operate with low voltages and have higher bandwidth and slew rate. The validity of the information and results are based on the circuits simulated in PSPICE.

The Root Locus and Polynomial Approach based Controller Comparison for Magnetic Ball Suspension System
Gurunayk C. Nayak, Praveen Kagatikar, Amit Jadagoudar
DOI: 10.17148/IJIREEICE.2015.3302
Abstract: Magnetic Levitation System (MLS) is an example of a non-linear and inherently unstable system. To overcome this instability an electromagnet will have to be constructed. The current in the electromagnetic coil is to be varied suitably using a compensator to generate varying magnetic field and hence a varying force to be exerted on any object in its vicinity. Two approaches were followed to design compensator. Firstly Root locus approach where in the pole in unstable region is moved to stable region. Another approach is Inward approach where in the poles are placed at desired location & co-efficient of compensator are obtained.

A Survey Approach – Multiprocessing on FPGA using Light Weight Processor
Shivaraja B G, Shankar B B, Praveen J, Raghavendra Rao A
DOI: 10.17148/IJIREEICE.2015.3303
Abstract: These Multiprocessors have been widely used in modern high performance embedded system to meet the computational needs of smart, real time applications spread across multiple domains. While custom IPs (InteUectual Property) on FPGA based systems are commonly used, multiprocessing on FPGAs have not been explored enough due to concerns about meeting a right trade-off between area usage, achievable performance, and the required design time. Multiprocessor embedded systems (MESes) are a very promising approach for high performance yet relatively low-cost computing. This paper presents an implementation of a multiprocessing system on FPGA using multiple light weight soft processors (LWP) that work in conjunction with a custom hardware to achieve balanced performance to resource ratio. As an example we have implemented a TDEA (Triple Data Encryption Algorithm).simulation is done by using Xilinx and implementation is done by using FPGA.

Improved Carrier Function and Optimal Structure for Stepped Wave Inverters
A.Mohandoss, K.Sivaramachandran, R.Radhakrishnan
DOI: 10.17148/IJIREEICE.2015.3305
Abstract: Multilevel inverters include an array of power semiconductor devices and capacitor voltage sources, the output of which cause voltages with stepped waveforms to have compact distortion. The term multilevel starts with the three-level inverter introduced by Nabae et al. The most attractive features of multilevel inverters include output voltages with extremely low distortion, lower dv/dt, input current with very low distortion, generate smaller common- mode (CM) voltage (thus reducing the stress in the motor bearings), lower switching frequency, etc. The main advantage of this topology is that it does not need additional diodes or capacitors for implementation. The operation of the flying capacitor multilevel inverter topology is based on the connection of capacitors, without using extra diodes. The most important advantage of this topology is that the number of switching combinations through which a same output voltage level can be achieved and hence allows a better distribution of the energy demanded from the capacitors. A new topology has to be proposed that provide higher number of level with optimum number of devices and dc voltage sources. A generalized structure has to be derived that brings easier implementation for desired output voltages for medium voltage applications. Also a new modulation technique is proposed which enhances the fundamental voltage and reduces the Total Harmonic Distortion (THD).

DOI: 10.17148/IJIREEICE.2015.3307
Abstract: In digital communication, there is a need of different modulation technique (such as ASK FSK PSK) to convey a message signal. A Universal modulation is the solution to obtain different modulation techniques. For the implementation of Universal Modulator on FPGA, different architecture have been proposed. One of the technique way to realize the Universal Modulator is Look up table (LUT). Here the CORDIC architecture is used for efficient realization of Universal Modulator. The coordinate rotation digital computer (CORDIC) algorithm is widely used in various technological fields such as digital signal processing (DSP), biomedical signal processing, robotics, communication systems, image processing etc. For simple shift and add operation, CORDIC based systems are increased drastically. For the realization of Amplitude modulation, Frequency modulation and Phase modulation, this Universal Modulation is used. The generation of SIN and COS output values will are tested for a given input angle (θ) value. The universal modulator will be designed around the CORDIC algorithms which can generate all most all digital modulation schemes such as ASK, PSK, FSK.

Robust DCT Watermarking for Digital Images
Sanjeevani Subhash Kagade, Prof.Dr. Kanade Sudhir Siddheshwar
DOI: 10.17148/IJIREEICE.2015.3308
Abstract: Owing to personal computers being applied in many fields and Internet becoming popular and easier to use, most information is transmitted with digital format. Therefore, data copying and back up are more and more easier in the world wide web and multimedia. The copyright and authentication gradually lose their security. How to protect intellectual property becomes important in technical study and research. Recently, the watermarking technique was proposed to solve the problem of protecting the intellectual property. In this paper, a watermark embedded in the host image by DCT transform has been proposed. There are several papers using the same manner to embed watermark into middle-band coefficients of DCT block. The Joint Photograph Expert Group (JPEG) image compression usually discards the high-band frequency in DCT block including some middle-band data. In this paper the lower-band coefficient of DCT block was employed, since it is robust against the attack by the JPEG. In order to improve the imperceptions, only one bit was embedded in each coefficient of a DCT block. The experimental results show the proposed approach is correct.

Anand Mickky, Pratibha Tiwari
DOI: 10.17148/IJIREEICE.2015.3310
Abstract: This paper presents a simulation and performance analysis of speed control of brushless DC motor using FOPID with LQR. DC motor is widely used in industries even if its maintenance cost is higher than the induction motor. Speed control of DC motor is attracted considerable research and several methods are evolved. The LQR controller is the very commonly used compensating controller. This paper presents a comparison of time response specification between conventional Fractional order Proportional- Integral-Derivatives (FOPID) controller and Linear Quadratic Regulator (LQR) for a speed control of a separately excited DC motor. A class of fractional order systems having single non-integer order element which show highly sluggish and oscillatory open loop responses have been tuned with an LQR based FOPID controller. The goal is to determine which control strategy delivers better performance with respect to DC motor‟s speed. Performance of these controllers has been verified through simulation using MATLAB/SIMULINK software package. According to the simulation results, liner quadratic regulator method gives the better performance, such as settling time, steady state error and overshoot compared to FOPID controller. This shows the superiority of liner quadratic regulator method over FOPID controller.

DOI: 10.17148/IJIREEICE.2015.3315
Abstract: In current 4G systems growing demand of multimedia services and the growth of internet related contents lead to increasing interest to high speed communications. One indispensable problem of the wireless channel is fading, which can be mitigated by diversity. There are various coding methods to achieve high reliability for Multiple Input Multiple Output- Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems earlier. Recently, Space Time Block Codes (STBC) have gained much attention as an effective transmit diversity technique to provide reliable transmission with high peak data rates to increase the speed and performance of wireless communication systems. This paper presents the performance evaluation of OFDM system, in which fading is reduced by using diversity techniques along with coding methods under various fading channels such as Rician and Rayleigh fading channels. In this work, a performance criterion such as Bit Error Rate (BER) for low Signal to Noise Ratio (SNR) ranging from 10dB to 20dB is analyzed. The BER for OFDM system without including STBC is 1.776x10-3 and including STBC is 1.621x10-3 over Rician Channel. Whereas, over Rayleigh channel the BER for OFDM system without including STBC is 1.834x10-5 and including STBC, it is reduced to 6.345x10-6 for the same SNR of 14dB. Thus, OFDM system with STBC provide high data rate with good reliability.

DOI: 10.17148/IJIREEICE.2015.3319
Abstract: Induction motor for many years has been regarded as the workhorse in industrial applications. An induction motor can run only at its rated speed when it is connected directly to the main supply. However many application need variable speed operations. With the invention of variable voltage variable frequency drives (VVVF), the use of an induction motor has increased. Variable voltage variable frequency control provides a simple and cost efficient method for open-loop speed control of three phase induction motor. This technique is popularly known as V/f control. In this paper principle and operation of V/f drive is summarized. This paper include experimental results of Voltage, Current and Speed on different frequencies which shows that induction motor speed is vary according to frequency input and simultaneously supply voltage is controlled to maintain V/f ratio constant.

Designing an Efficient Image Encryption-then Compression System
B.Suneetha
DOI: 10.17148/IJIREEICE.2015.3321
Abstract: In many practical scenarios, image encryption has to be conducted prior to image compression. This has led to the problem of how to design a pair of image encryption and compression algorithms such that compressing the encrypted images can still be efficiently performed. In this paper, we design a highly efficient image encryption-then- compression (ETC) system, where both lossless and lossy compressions are considered. The proposed image encryption scheme operated in the prediction error domain is shown to be able to provide a reasonably high level of security. We also demonstrate that an arithmetic coding-based approach can be exploited to efficiently compress the encrypted images. More notably, the proposed compression approach applied to encrypted images is only slightly worse, in terms of compression efficiency, than the state-of-the-art lossless/lossy image coders, which take original, unencrypted images as inputs.

DOI: 10.17148/IJIREEICE.2015.3322
Abstract: Electrocardiogram is an important tool in diagnosing the condition of the heart. Extracting the information from the Electrocardiograph is an important task in determining the variations of the electrical activity of the heart. ECG feature extraction plays a major significant role in diagnosing the most of the cardiac diseases. One among the major cardiac diseases is arrhythmia which is abrupt and abnormal heart beat. In case of arrhythmia heart doesn’t pump sufficient blood required for the human body and sudden cardiac death may happen and this can even damage vital organs such as brain, heart, etc. of the body positions. So it is very much needed to determine conditions of arrhythmia and should take necessary measure before the patient reaches some serious condition. Hence in order to find out arrhythmia ECG signal should be analyzed. Analyzing the ECG signal manually is a tedious process so number of researches has been done recently for analyzing the ECG signal based on fuzzy logic method, artificial neural networks, genetic algorithms and support vector machines and using other analysis techniques. This proposed paper discusses different ECG analysis techniques and provides comparative study of various methods of such techniques proposed by researchers in the previous articles. as both an instruction set and as a template into which you can type your own text.

DOI: 10.17148/IJIREEICE.2015.3323
Abstract: Majority of the population, especially the people older than 65, suffer from Chronic Heart Failure leading to frequent hospitalizations which results in high health expenditure. So, we have developed a complete and integrated Information and Communication Technology system on LabVIEW platform that enables the doctors to diagnose and monitor the CHF patients from distance. This system measures the heart rate and blood pressure of the patient through heart rate sensor and blood pressure sensor. The output from these sensors are transmitted to the remote system via Bluetooth. It is then transmitted to the Hospital Information System by using LabVIEW tool. This enables the CHF patients to daily collect vital signs at home and automatically send them to the Hospital Information System and it also allows the physicians to monitor the patients from distance and to take timely actions in case of necessity.

Development of Infrastructue for Residential Load to Reduce Peak Demand and Cost of Energy in Smart Grid
Hemant I. Joshi, Hemish R. Choksi
DOI: 10.17148/IJIREEICE.2015.3327
Abstract: The renewable energy sources like solar and wind power will be economical in future due to upward pressure in fossil fuel prices, progress in renewable technologies as well as economy scale resulting from large scale production of renewable energy sources. As the usage of renewable energy sources will increase, decentralized supply and demand side management will be used instead of conventional centralized supply side management in future smart grids. Smart meters offer solution to this by allowing more sophisticated measurement of consumption and the implementation of real time pricing. Using power scheduling of appliances we not only reduce the peak demand but operate the appliances when price is low. In this paper real time price based demand response management for residential appliances using intelligent metering and billing system using smart meter is described. Next generation meters will use Automated Meter Reading (AMR) and provide more sophisticated services to the customers. Here architecture of smart grid that is capable of automated reading, alert management (for various events like exceeding peak demand, exceeding monthly target bill etc.) and web dash board to view and control the consumption of various appliances is introduced.

Abstract: This paper investigate the problem regarding the minimization of the power of the base station by using the cell zooming technique. In this paper, we mainly focused on reducing the power consumed at the base station end, whereas most of the power minimization related work in the literature today is focused on the mobile end only. Cell zooming is a technology that promises to minimize the resource utilization. This technique is designed to save the energy consumed by the base station by maintaining the quality of services. To understand the working of the cell zooming techniques centralized algorithm is a very basic way.

Efficient FPGA Implementation of Variable precision floating point Arithmetic using VHDL Language
Mr. Varun, Dr. Vinod Kapse
DOI: 10.17148/IJIREEICE.2015.3346
Abstract: Computers were originally built as fast, reliable and accurate computing machines. It does not matter how large computers get, one of their main tasks will be to always perform computation. Most of these computations need real numbers as an essential category in any real world calculations. Real numbers are not finite; therefore no finite, representation method is capable of representing all real numbers, even within a small range. Thus, most real values will have to be represented in an approximate manner. The scope of this paper includes study and implementation of Adder/Subtractor and Multiplication ,Division and Square root functional units using HDL for computing arithmetic operations and functions suited for hardware implementation. In this paper, we present pipelined architecture to implement Variable bit floating point Arithmetic in Field Programmable Gate Array (FPGA). Specially we designed square root of floating point numbers using modified non restoring square root algorithm. This algorithm has been optimized by eliminating a number of elements without compromising the precision of the square root and the remainder. The algorithms are coded in VHDL and validated through extensive simulation. These are structured so that they provide the required performance i.e. speed and gate count. It is an improvement over non restoring algorithm as it uses only subtract operation and append 01 instead of add operation and append 11. Here the basic building block is Controlled Subtract Multiplex (CSM). By using this module, the algorithm can be designed for any number of input bits. This strategy offers an efficient use of hardware resources. The modified non restoring algorithm is designed using VHDL and implemented on ALTERA cyclone II FPGA. The implementation results show reduced area in terms of logic elements when compared to restoring algorithm.
