Abstract :
The performance analysis of MC-DS-CDMA (multi-carrier coded-division multiple-access) system working in multipath fading channel with unbalance branch gain is investigated in this paper The model of the multipath fading is characterized by Nakagami statistic distribution. We establish and derive the model for MC-DS-CDMA systems working in unbalanced channel gain with Nakagami fading statistics. The average BER (bit error rate) is calculated and compared to the special case of the published results. Basically, some studied results from this paper can be implied to improve the system performance for the MC-DS-CDMA systems in 3G or B3G wireless communication systems.
