Ber performance analysis of certain Multiuser detection techniques for Channel capacity enhancement in Cdma mc cdma systems

Abstract

In the current era of information technology wireless broadband newlinecommunication industry is growing rapidly New enabling technologies such as newlinechannel overloading and Multi carrier Code Division Multiple Access MCCDMA newlineare shaping the future of wireless communication systems However newlineresearch efforts in improving receiver performance of Code Division Multiple newlineAccess CDMA and MC CDMA have received limited attention so far Hence newlinethere is a potential need for innovative receiver designs to meet out the modern newlinerequirements newlineThe main objective of this research work is to device efficient multiuser newlinedetection and interference cancellation IC algorithms for CDMA MC CDMA newlinesystems to enhance the performance This thesis attempts to investigate the IC newlineand interference mitigation techniques for CDMA MC CDMA system in newlinevarious channel conditions with a view to minimize the Bit Error Rate BER and newlineenhance the channel capacity newline newline
