摘要

本文提出了两种在多媒体CDMA系统中最小化传输时间的动态资源分配方案.对于多媒体业务

当我们让传输时间是可变数据速率的函数时

该方案即可找出当前用户组的最优数据速率集

以使系统的传输时间最小.文中给出并证明了计算最优速率集和对应最小传输时间的方法

归纳了当系统中业务变化时

根据变化的QoS要求和用户数目进行动态资源分配的流程.最后

与最大吞吐量动态资源分配方案进行了比较

给出了三种方案在吞吐量和传输时间上的差异.

Abstract

In this paper

two resource allocation schemes are proposed to minimize the transmission time in multimedia CDMA systems.When the time is expressed as a function of various data rates

the optimum set of data rates for concurrent user groups to achieve minimum transmission time can be derived. The approach of calculating the optimum set of data rates and the minimum transmission time is presented and proved.For various traffic conditions

we proposed dynamic resource allocation schemes according to various QoS requirements and the number of users.Finally

the two new schemes are compared with the maximum throughput resource allocation scheme

and the differences of these schemes in throughput and transmission time are presented.
