本文采用一种新的平均周期分析方法对时隙式随机多址系统进行了分析,得到了系统的报文分组发送成功的平均长度公式、报文分组发生碰撞的平均长度公式和空闲时隙的平均长度公式,并在讨论了系统的捕获效应特性和冲突分解特性后,给出了系统的吞吐量.最后,还给出了系统的计算机模拟实验结果. In this paper, a new average period analysis method is used to analyze the slotted randomized multiple access system. The average length of the successful packet sending system, the average length of the packet collisions and the free slots Average length formula, and after discussing the system’s capture effect characteristics and conflict resolution characteristics, the throughput of the system is given.Finally, the results of the computer simulation of the system are also given.
