摘要 分析了密集多径环境下码复用差分混沌移位键控(code-shifted differential chaos shift keying,CS-DCSK)超宽带(ultra wideband,UWB)通信系统在单个和多个窄带干扰(narrow band interference,NBI)信号下的比特误码率(biterror rate,BER)性能。建立CS-DCSK UWB系统仿真模型,并通过采样扩展方法推导出BER的表达式,从而得到系统在不同干扰条件下的BER性能。分析和仿真结果表明,NBI信号对系统有明显干扰作用,但系统性能在不同频率干扰下保持稳定。 The performance of code-shifted differential chaos shift keying（CS-DCSK） ultra wideband（UWB） communication system under single or multiple narrow band interferers is analyzed in dense multipath environments.The bit error rate（BER） is derived on the basis of the sampling expansion approach under different interference strengths.The simulations and analyses demonstrate that the NBI signal interferes significantly the performance of system.However,the system performance keeps stable under interferer with different frequencies.
