Abstract
In this paper, the average bit error probabilities of Multi-Carrier Code Division Multiple Access (MC-CDMA) system over the generalized fading channels are derived and evaluated. The effects of gain unbalance between branches on the bit error rates of the system are also examined. The numerical results indicate that the performance of MC-CDMA becomes better as the fading factor m increases. Besides, if the number of the carriers gets more, the error probability of the system will decrease. Remarkably, the effects of gain unbalances between branches on the MC-CDMA system will suffer more performance degradation.
