摘要

研究了非理想PN码同步和BER共同影响下

基于DS/CDMA的移动Ad hoc网络传输范围.提出一种非理想PN码同步下每时隙期望前进距离EFP

EFP为本地吞吐量与链路距离的乘积

通过最大化EFP可以获得节点最佳传输范围.数值结果表明非理想PN码同步降低了EFP的值

并且每个节点平均发送数据包的最佳概率也不同于目前已有的研究结果.

Abstract

The effect of PN code synchronization and BER together on transmission ranges in DS/CDMA Moble Ad hoc networks(MANET)is studied.The expected forward progress per slot that is a product of local throughput and link distance is put forward.The optimum transmission ranges can be obtained by maximizing expected forward progress.The results show that the probability of PN synchronization decreases the expected forward progress per slot compared with previous results.The results also show that the optimum probability

of each terminal transmitting a packet is different from previous results.
