摘要

提出了一种基于等效带宽分配的媒质接入控制(MAC)方法

它针对CDMA系统是“误码率受限”型系统这一特点

将多媒体业务不同的误码率要求映射为等效带宽。系统根据流量动态地将等效带宽分配给不同业务。仿真结果表明

相比与已有的CDMA系统的MAC方法

本方法具有更好的吞吐量性能。

Abstract

A medium access control（MAC） protocol with effective spectral bandwidth distribution was proposed for the CDMA network carrying multi-service traffics.Based on the “BER limited” characteristics of the CDMA system

the protocol maps the diverse BER requirements of multimedia services into the effective spectral bandwidth.The ef-fective bandwidth was dynamically distributed to different services according to the traffic of the system.The simu-lation results show that the performance of the proposed system in terms of throughput is better than that of the exist-ing systems.
