阐述了 S-TDMA系统中暴露终端问题的形成 ,给出了解决这一问题的一种方案。并提出一种新的自组织时分多址数据链网络性能分析方法——概率周期分析法。通过引出系统状态熵概念 ,将时隙状态的停留时间和状态转移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占系统状态熵之比作为评价信道吞吐量的新方法。仿真结果表明 ,采用了这一方案后系统性能将大大改善 The formation of the exposed terminal in S-TDMA system is expounded, and a solution to this problem is given. And proposes a new method of performance analysis of self-organizing TDMA data link network-probability cycle analysis. By introducing the concept of system state entropy, the time-slot residence time and state transition probability are introduced into the analysis model at the same time, and a ratio of the state truth value of the time slot in the state of successful transmission to the system state entropy is given as the evaluation channel A new way of throughput. The simulation results show that the system performance will be greatly improved after adopting this scheme
