摘要

本文主要是基于一种并行组合直扩通信系统，研究其中的信息－分组映射问题，指出该映射对系统的影响不容忽视，并介绍一种确定近最佳映射的简便易行的方法，即“图匹配法”．计算机模拟结果表明，信息－分组映射的优化是重要的，而且按本文提出的方法所得到的映射是足够好的．文中还较全面地比较了几种直扩通信方式，结果表明，这种并行组合直扩通信方式具有相对较高的效率和较低的复杂度

Abstract

The information-combination mapping is mainly investigated based on a parallel combinatory DS/SS communication system.It’s shown that the effect of this mapping on the system is not negligible and.an easily operated method called"graph matching″to get the suboptimal mapping is presented.Computer simulation results demonstrate that it’s important to optimize the mapping

and the mapping determined with the proposed method is good enough.By a comparison of several DS/SS communication schemes

it can be found that this parallel combinatory DS/SS communication system has higher efficiency and lower complexity relatively.
