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。仿真结果表明该相关解调方案对信道噪声有很好的鲁棒性 A new demodulation scheme of chaotic spread spectrum sequence is discussed. The signal can be effectively demodulated by using the good statistical properties of chaotic sequences. In this paper, the analytical expression of the bit error rate of the scheme is deduced, and the intrinsic relationship between the number of chaotic spread spectrum chips and the channel noise and error performance is found out. Simulation results show that the proposed demodulation scheme has good robustness to channel noise
