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 This paper is mainly based on a parallel combination DSSS communication system, studying the information-packet mapping problem, pointing out that the impact of the mapping on the system can not be ignored, and introducing a simple and easy method to determine the near best mapping, namely “ Map matching method. ” Computer simulation results show that the optimization of information-packet mapping is important, and the mapping obtained by the proposed method is good enough. The paper also compares several DSSS methods more comprehensively. The results show that this parallel combination DSSS method has relatively high efficiency and low complexity
