Muti-Carrier CDMA overview with BPSK modulation in Rayleigh channel

Multi-carrier code division multiple access (MCCDMA) is an attractive choice for high speed wireless communication as it mitigates the problem of inter symbol interference (ISI) and also exploits frequency diversity. In order to support multiple users with high speed data communications, the MC-CDMA technique is used to address these challenges. In this paper working of Transmitter and Receiver model of MCCDMA system is presented. This work also derives simulation through MATLAB of average bit error rate (BER) versus bit energy to noise ratio (Eh/No) of Multi Carrier Code Division Multiple Access (MC-CDMA) systems using various detection techniques which are used for both uplink & downlink MCCDMA systems i.e. Maximal Ratio Combining (MRC) and Equal Gain Combining (EGC) with synchronization errors over Rayleigh channel using BPSK modulation and Additive White Gaussian Noise, which shows the reduction in BER performance.
