摘　　要：讨论了一种新型的混沌扩频序列的相关解调方案，通过利用混沌序列良好的统计特性可以有效地解调出信号。文中推导出该方案误码率的解析表达式，发现了混沌扩频序列码片数和信道噪声与误码性能的内在联系。A new correlation demodulation scheme for the chaotic DS/SS signal is presented in this paper. DS/SS signal can be demodulated efficiently by using the statistical characteristics of the chaotic sequence. The mathematical formulas of BER are given and verified by simulation results theoretically and empirically. The relationship of the chip of chaotic sequence, noise and performance of this scheme is discussed.
