摘　　要：本文分析室内无线多径衰落信道中直接序列/慢跳频(DS/SFH)混合扩频多址通信系统的性能。系统采用DPSK调制和检测前合并的分集接收技术。通过对多址干扰和多径干扰使用高斯近似的方法,我们得到了系统的误码率。The performance of noncoherent reception in hybrid direct-sequence/slow-frequency-hopped (DS/SFH) spread spectrum multiple access (SSMA) communication systems operating through indoor wireless multipath and fading channel is investigated. The system with differential-phaseshift keying(DPSK) modulation and predetection combining is examined. We obtain approximations for the multiuser probability of error by using a Gaussian app.roximation for the multiple access and multipath interference
