Research on Performance of Multi-user Cooperative Communication Systems Based on CS-DCSK

协作通信作为无线通信发展最快的研究领域之一，吸引了众多的研究者。而以混沌信号为载波的非相干混沌通信是一种有潜力的短距离通信方式，具有良好的抗多径衰落能力。基于差分混沌移位键控(DCSK：DifferentialChaosShiftKeying)和码复用差分混沌移位键控(CS-DCSK：Code-ShiftedDCSK)的协作通信系统能够保证非相干混沌系统优点的同时获得协作分集增益，是近期混沌通信研究的一个热点。本文从性能分析入手，研究了基于CS-DCSK的多用户协作通信系统，具体开展的工作如下： (1)首先建立了基于一般化的码复用差分混沌移位键控(GCS-DCSK：GeneralizedCS...Cooperative communication, as one of the fastest growing research in the wireless communication field, attracted the attention of many researchers. Incoherent chaotic communication, which chaotic signal as its carriers, is a kind of potential short distance communication, and has a good ability to resist multipath fading. The cooperative communication system can ensure the advantages of the incohe...学位：工程硕士院系专业：信息科学与技术学院_工程硕士(电子与通信工程)学号：2332013115327
