摘要
本文以高斯近似的方法,对DS/CDMA长码系统在Rayleigh衰落多径环境下的性能进行了分析,得出了误码下限,并讨论了扩频增益与多址、多径的关系。
The performance of long pseudonoise code DS/CDMA system in multipath Rayleigh fadingenvironment with G aussian approximation is evaluated. The lower beund of bit error probability is ob-tained,and the relationships between the spread gain and the multi-access and multipath is discussed.
