摘要
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 .
SAMA is a new concept to spread spectrum packet radio network and random multiaccess.Seeing that variance of packet length is important to performance of packet network,both analysis and simulation schemes for selection of optimal packet length in SAMA system are presented in this paper based on performance analysis of SAMA.Schemes are generalized for common DS/SSMA packet network easily.
