摘要
用有限用户离散时间损失制系统对蜂窝移动通信基站进行建模,利用Markov链方法,给出稳态下系统每一时隙上发生损失的概率、平均信道利用率和平均吞吐率等性能指标。并通过数值仿真解释了该模型对数字蜂窝移动通信网络设计及性能分析的应用。
In this paper, the base station of cellular mobile communication is modeled with finite user population discrete time queueing system. The method of Markov chain is used to derive the performance index such as probability of loss in one slot, the mean throughput of the system, and the utilization ratio of channels. And through the numerical simulation, the effect of the model to the cellular mobile communication networks is discussed.
