Analysis of the BER Performance of Chip-Level Differential Detection for Frequency Domain Spread Spectrum System

  • 摘要: 该文提出了一种频域扩频系统中的差分检测方法:频域扩频码片级差分检测.通过利用判决变量的矩生成函数,并采用鞍点近似的分析方法,得到了频域扩频码片级差分检测的误码率性能的解析表达式,同时进行了仿真验证.分析和仿真结果表明,频域扩频码片级差分检测具有抵抗频率选择性衰落的能力,在信道的相干带宽不小于两个码片对应的频带宽度的前提下,随着信道多径时延扩展的增加,其误码率性能有进一步的提高.
