扩谱ALOHA多址访问 (SAMA)是近年对传统无线扩谱分组通信及随机访问多址方式全新的认识 .本文在系统分析SAMA基本性能的基础上 ,研究了对分组网络工作性能将产生重大影响的最优数据包长度的分析选取方法 ,给出了理论分析与仿真两种方案 ,分析方法及结果可以容易地推广到一般直接序列扩谱分组网络之中 .
Spread spectrum ALOHA Multiple Access (SAMA) is a new understanding of traditional wireless spread spectrum packet communication and random access multiple access methods in recent years.Based on the systematic analysis of the basic performance of SAMA, this paper studies the significant impact on the working performance of the packet network The optimal packet length of the analysis and selection method, given the theoretical analysis and simulation of two programs, analysis methods and results can be easily generalized direct sequence spread spectrum packet network.
