Certain investigations on multiple Input and multiple output receivers For wireless channel

Abstract

Multiple Input Multiple Output MIMO communication refers to a newlinetechnology that uses an array of antennas at both transmitting and receiving newlineside MIMO technology enhances performance factors such as speed data newlinerate bit error rate and link reliability without extra frequency and power newlineresources It also offers many potential advantages like diversity gain in newlinefading channel increased antenna gain interference rejection multipath newlinerejection Direction of Arrival DOA and spatial multiplexing and thus newlineincreases the robustness and reliability of the system with reduced Inter newlineSymbol Interference ISI and channel fading newlineMIMO receivers are complex receivers with more computations The newlinecoal of the thesis is to mathematically model simulate and study the newlineperformance of a Novel low computationally complex MIMO receiver newlineHence linear receivers are considered as an attractive low complexity newlinealternative compared to non linear optimal signal processing receivers For newlineany MIMO communication receiver the Bit Error Rate BER is very newlineimportant performance metric This thesis investigates about BER as a main newlinefactor for investigation in the presence of uncorrelated Rayleigh channel The newlinemathematical modeling is done and simulation analysis is carried out using newlineMatlab Communication tool box version 7 0 Only Rayleigh fading channel is newlineconsidered throughout the thesis newline newline
