摘要/Abstract

摘要：

用有限用户离散时间混合消失系统对无线通信系统中基站进行建模。利用Markov链方法，给出稳态下系统每一时隙(slot)上阻塞概率、平均等待时间、平均信道利用率和平均吞吐率等无线通信网络的性能指标。并通过数值仿真解释了该模型对数字无线通信网络设计及性能分析的应用。

关键词: 有限用户, 混合消失系统, 阻塞概率, 有限等待空间

Abstract:

In this paper modeling the base station of wireless communication networks with finite user population discrete time loss and delay system. And using the method of Markov chain we derive the performance index such as probability of loss in one slot, the mean waiting time of the mobile stations, the mean throughput of the system, and the utilization ratio of channels. And through the numerical simulation, we discuss the effect of the model and the applications on design and performance analysis of digital wireless communication networks.

Key words: finite user population, loss and delay system, blocking probability, finite waiting room
