    Abstract

    The authors have described a technique for determining the performance of a direct-sequence spread-spectrum multiple access (DS-SSMA) system with DPSK modulation and diversity for a variety of multipath Rayleigh-fading channels, and applied it to two models of an indoor environment. They have shown that the system with DPSK modulation and selection diversity compares well with a similar system using coherent PSK modulation. Predetection combining gives a significant improvement in performance over selection diversity for high-diversity orders. The performance with selection diversity for the two models indicates that the system may be robust to changes in the delay distributions and average path-power profiles of the multipath Rayleigh-fading channel.
