摘要

本文分析了一种新的多通道话音／数据综合ＶＳＡＴ系统的Ｓ－ＡＬＯＨＡ性能，并给出了数值计算结果；从中可看到该协议既能提供较高的吞吐量，又能有效地减小话音时延，并能协调话音和数据之间对性能要求的差异，文中考虑了Ｓ－ＡＬＯＨＡ中分组达到时间抖动的影响．文中还讨论了话音在重负载的条件下可占用数据通道的动态分配方案，并给出了动态分配的算法。

Abstract

VSAT is one of primary trends of future satellite communications. Most of recent VSAT system are used as a data network or a voice network in which data can be transfered in voice channels. Such a system can not give a higher effieiency of channel utility and perform a voice/data integration well. The performance of SALOHA for multichannel voice/data integration VSAT is discussed and the numerical results are obtained. It is concluded that the protocol can provide a higher throughput

lessen the voice acess delay effectively and coordinate the difference between voice and data. Under the heavy load of voice the data channel can be occupied by voice and a dynamic assigment algorithm of channel is acquired.
