Fourth Generation wireless communication demands a better multiple access technique for reducing the Multiple Access Interference (MAI) and Inter Symbol Interference (ISI) and to improve the bit error rate performance. MC-CDMA is the best candidate that would satisfy the demands of 4G wireless systems. MC-CDMA does not require more rake figers and it shows better performance than OFDM at low signal power in Ultra Wide Band (UWB) channel. UWB uses bandwidth above 20% of center frequency which severely suffers from frequency selective fading. This study analyses the performance of Orthogonal Frequency Division Multiplexing (OFDM) and Direct Sequence (DS) CDMA systems. The simulation results shows that the MC-CDMA performs well interms of BER comparatively with other techniques in wide band channel. UWB Saleh-Valenzulea channel model proposed by intel is used in the simulation for analyzing the performance of MC-CDMA systems. |
