时隙式随机多址系统中两种平均周期划分

Study on Two Average Cycle Schemes for Slotted RandomMultiaccess Channel

随着卫星通信系统、无线分组网络和计算机通信网络的迅速发展，随机争用多址接入的传输理论也得到了极大的丰富和发展，其应用也越来广泛。本文在文献［８］的基础上，对时隙式随机多址系统进行了研究，给出了两种新的平均周期划分，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。

With the rapid progress of satellite communication system, wireless packet networks and computer networks, the theory of random multiaccess channel has been developed enormously, and the applications are more extensive. At the basis of the reference,the new average cycle schemes for slotted random access channel were being analyzed by using the average cycle method. Analytic formulae for mean values of a successful period and a colliding period and an idle period are derived.
