| Abstract: | 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. |
