摘　　要：混沌技术与传统扩频通信相比能够很好的抗多径衰落信道,阐述了混沌通信的研究现状及其与传统的扩频通信的不同,分析比较了两种差分混沌移相键控的多址接入方案:WALSH-DCSK多址接入方案和CDMA-DC- SK多址接入方案。并通过实验仿真分析比较了这2种方案的性能优劣,实现复杂度等。Two kinds of DCSK multiple access scheme, WALSH-DCSK multiple access and CDMA-DCSK, are proposed and analyzed in this paper. We will explore which scheme works better and facilitate in accomplishment. Bit error rate have been derived numerically for different number of users and computer simulations have been performed to verify the results.
