摘要

研究了微蜂窝网络准同步码分多址(QS-CDMA)系统。为了抑制多址干扰(MAI)，提出了一种覆盖扩频码分多址系统。分析和仿真结果表明，与传统的串联方案相比，叠加扩展方案具有更好的系统性能。

An overlay spreading scheme for microcellular QS-CDMA system

A quasisynchronous code-division multiple-access (QS-CDMA) system for microcellular network is considered. The proposed QS-CDMA system employs an overlay spreading code allocation scheme in order to suppress the multiple access interference (MAI). It is shown, by analytical and simulation results, that, compared with the conventional concatenated scheme, the overlay spreading scheme exhibits better system performance.
