Abstract :
An analytical approach is developed to derive the expression of the Multiple Access Interference (MAI) and Bit Error Rate (BER) of a MC-DS-CDMA system using multiple receiving antennas with Maximal Ratio Combining (MRC), considering Rayleigh fading channel. The analysis is extended to RAKE receiver with Equal Gain Combining (EGC). The results are presented in terms of BER and improvement of receiver sensitivity due to diversity and multicarrier orthogonal modulation. It is noticed that there are significant improvement due to diversity as well as the number of subcarriers in MC-DS-CDMA system.
