N2 - In this paper, the average bit error rate (BER) performance of uplink and downlink Multicarrier Code Division Multiple Access (MC-CDMA) system using coherent maximal-ratio combining (MRC) and equal gain combining (EGC) receivers For frequency selective Nakagami fading channel were studied. The analysis that assumes different subcarriers experience independent lading channel, but not necessary identically distributed. Generalized BER expressions for both uplink and downlink with MRC and EGC receivers are derived. From the derived results, however, the performance of EGC is found to outperform the MRC in the downlink. On the other hand the MRC for uplink found to be the optimal compared with the EGC.
