Abstract
In this paper, we derive the expressions for Signal-to-Noise plus Multi Access Interference Ratio (SINR) without and with receive diversity considering Nakagami-m fading channel. The analysis is also extended to Rake receiver with Maximal Ratio Combining (MRC) technique with multiple receiving antenna. The results are presented in terms of BER and improvement of receiver sensitivity due to diversity. Finally, optimum values of system parameters like number of OFDM sub-carrier, optimum code length and order of receive diversity for a given BER are determined. It is noticed that there is significant improvement due to receive diversity, higher order code length as well as OFDM sub-carrier in a MC-DS-CDMA system.
