Abstract: The Quadruple System is a typical control system with nonlinear, coupling and time delay characteristics which can be used to test the applications of different control algorithms on complex systems. The aim of the process is to keep the liquid level in the tanks at the desired values. Here, Modified Model Reference Adaptive Control is proposed and is applied to the four tank system to test its performance. Time domain parameters like Settling time, Rise time and Mean Square Error are used for evaluating the performance of the controllers. The response of the controller is verified and is compared with other control algorithms through simulation. The performance of the closed loop system is simulated using LabVIEW software. The method used here is validated using the simulated results.

Abstract: CDMA (code division multiple access) is one of the most developing technology in modern mobile communication. It has gained widespread international acceptance by cellular radio system operators as an upgrade that will dramatically increase both their system capacity and the service quality. The core principle of spread spectrum is the use of noise-like carrier waves, and, as the name implies, bandwidths much wider than that required for simple point-to- point communication at the same data rate. Most third generation mobile communication systems are using CDMA as their modulation technique. In CDMA interleaving is used for multiplexing of several input data over shared media. In CDMA system different type of interleaving schemes are used. In this paper we analyze the performance of these interleaving schemes in multipath fading and additive white Gaussian noise (AWGN) channels. We conclude that different interleaving schemes has different data rates and bit error rate.

Abstract: The objective of digital subscriber line (DSL) is to propagate signal from the transmitter to the receiver over telephone lines. In communication industry asymmetric digital subscriber line (ADSL) is widely used because it can handle both phone services and internet access services at same time. As the communication industry develops, its main concern is to maximize the user handling capacity of communication systems. For this purpose, ADSL uses Discrete Multitone (DMT) modulator with QAM bank. But as the number of users increases the system complexity and interference also increases. The communication channel is not free from the effects of channel impairments such as noise, interference and fading. These channel impairments caused signal distortion and signal to ratio (SNR) degradation. One method that can be implemented to overcome this problem is by introducing channel coding. Channel encoding is applied by adding redundant bits to the transmitted data. The redundant bits increase raw data used in the link and therefore, increase the bandwidth requirement. So, if noise or fading occurred in the channel, some data may still be recovered at the receiver. While at the receiver, channel decoding is used to detect or correct errors that are introduced to the channel. So first design an asymmetric digital subscriber line (ADSL) with discrete multitone (DMT) modulator having 16-QAM banks. Then analyze this ADSL system with different interleaving schemes to reduce the interference and improve the performance of system

Abstract: DVB-T is the most widely used standard for interactive television. DVB-T uses the MPEG-2 standard for coding the data, as well as Forward Error Coding, Reed Solomon Coding and Convolutional coding to make the signal robust against the high amount of error that comes with transmission. It also uses QPSK to modulate the signal, which makes the information be encoded in the phase instead of the amplitude, which also helps with making the signal robust enough for the channel. But due to increase in number of users and changing needs of users in the field of communications and entertainment, there are new challenges that the currents standards are not able to satisfy. So as the number of users increases the system complexity and interference also increases. The communication channel is not free from the effects of channel impairments such as noise, interference and fading. These channel impairments caused signal distortion and signal to ratio (SNR) degradation. This problem can be overcome by implementing the system with different modulation and error detection and correction schemes. So first design a DVB-T system with convolutional coding and OFDM transmitter. Then analyze this system with different modulation schemes such as 64-QAM and QPSK modulation, and find the best suited modulation scheme with lowest bit error rate. Then again analyze this system with different error detection and correction schemes such as Reed-Solomon (RS) encoding and Cyclic Redundancy Check (CRC) encoding to reduce the bit error rate and improves the performance of system.

Abstract: Most people know that “going green” is important for the environment. But what many don’t realize is that it can also be important for businesses, both in terms of cost savings and being socially responsible. Green computing is the practice of using information technology in an environmentally sustainable way. This includes everything from reducing energy consumption to recycling old equipment. There are many benefits to green computing. Perhaps the most obvious is that it can save businesses money. For example, by reducing energy consumption, businesses can lower their utility bills. They can also save money on disposal fees for electronic waste. In addition, going green can help businesses build goodwill with consumers and other stakeholders who are interested in environmental sustainability. Finally, some government incentives are available for businesses that adopt green practices. Despite the benefits, there are some challenges associated with green computing. One is that it can require a significant upfront investment, which may not be feasible for all businesses. Additionally, changing business practices can be difficult and time-consuming. However, these challenges should not discourage businesses from doing their part to protect the environment through green computing practices.
