摘要

本文给出了一种ＣＤＭＡ系统。它通过变化分配给每个用户的码数来提供变速率业务。系统工作于多径衰落信道。对于宏区、微区和微微区的信道模型，还给出了一种不同环境下对ＣＤＭＡ系统误比特率的近似方法，该方法仅依赖于多径能量的一二阶矩。最后，对综合话音、图像业务在不同信道模型下的误比特率性能作了分析。

Abstract

In this paper

we propose a Code Division Multiple Access（ CDMA） based system to providevariable rate services by varying the number of codes assigned to a user. For the macro-

micro-

picrocell chan-nel models

an approximation to the bit error probability in different environments is given which depends only onthe first and second order moments of the multipath energies. We then analysize the BER’ S performance of asystem with integrated voice and video traffics.
