摘要：

BER Performance of Multi-Code Biorthogonal Code Select CDMA system is shown in this paper. MC Biorthogonal CS/CDMA system employs truncation scheme to make binary signals so that it can reduce the value of peak to average power ratio(PAPR). Thus, this system enables to realize cost-efficient and power-efficient RF modules, still maintaining good overall BER performance. However, the nonlinear characteristics of Clipping cause some randomness in specific signal-to-noise ratio. Lloyd -Max Quantization is compared with Clipping for performance improvement. BER performance is shown in AWGN and multi-path fading channels.
