Analysis and comparison of Bit Error Rate variation with the change in number of antennas in a V-BLAST based MIMO system

Abstract: The number of users for applications based on broadband multimedia services like cellular phones, wi-fi, laptop, wireless networking, Bluetooth applications are growing very rapidly. This is the motivational cause for enhancing the tapping of frequency band. The MIMO antenna system can be used for efficient and faster communication. The Bit error rate is a parameter for judging that whether the communication held on transmission channel was appropriate or not. The reduced bit error rate with signal to noise ratio will be the demand of ideal communication system. Different technique are been utilized by communication system to retrive the information from received signal at receiver end. The V-BLAST is a technique developed in Bells labs USA, this technique can be use to design a comparative less complex system with increased efficiency. In this paper a novel information retrieving technology from a noisy phase shift keying modulated signal is discussed and analyzed. Here the effect of change in number of transmitter and receiver end antennas over BER of system is also been analyzed.
