BER Performance of DS-CDMA System over a Multipath Rayleigh Fading Channel Considering Path Gain Component and Noise Variance

摘要

The performance of DS-CDMA system is examined by the bit error rate (BER) performance of the system which is estimated by standard Gaussian approximation (SGA) with power control. The BER performance of multiple access system is studied over a fading channel such as frequency selective multipath Rayleigh fading channel. In this paper, the path gain component is considered as Rayleigh distribution and the effect of this path gain component and noise variance in BER performance of DS-CDMA system has been explained. In addition, optimum design parameters for a DS-CDMA system have been suggested.
