摘要

本文提出一种新的自组织时分多址(S-TDMA)数据链网络性能分析方法——概率周期分析法.一方面提出系统状态熵的概念

将时隙的状态停留时间和稳态概率同时引入分析模型中

给出了一种以时隙的处于成功传送状态的状态真值与系统的状态熵之比作为评价信道吞吐量的新方法;另一方面提出基于同信道干扰(CCI)准则的终端分区模型

分析隐藏终端在不同区域内对终端的影响.最后

提出了一种基于捎带帧技术的解决S-TDMA系统隐藏终端问题的方法.系统仿真的结果表明

该方法行之有效.

Abstract

A new method named Probability Cycle Analysis is proposed in this paper

which is used to analyze the performance of self-organized time division multiple access (S-TDMA) datalink system.By defining system state entropy

duration of slot state and state steady probabilities are stated

and an evaluation method on channel throughput adopting ratio of the true value of safe state to state entropy of system is presented in this paper.A terminal coverage partition model based on Co-Channel Interference (CCI) rule is also provided

which is used to analyze specifically the effect of hidden terminals in different areas.Finally

a solution to hidden terminals problem based on piggy frame technology is proposed.Simulation results show that the method is effective.
