利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.使用Markov链分析方法,给出了稳态下系统每一时隙上阻塞概率、平均等待时间、平均信道利用率和平均吞吐率等网络性能指标.而用数值仿真分析了系统缓存空间与系统负载与两类无线通信网的性能指标的关系.
The model of the base station of wireless networks is built based on the finite user population discrete time delay and loss system. The performances of the networks, such as the loss probability in one slot, the mean waiting time of the mobile stations, the mean utilization ratio and the mean throughput under stable state of the system, etc. are derived by the analysis method of Markov chain, The numerical simulation analyzes the relationship between buffer size, system load and the performances of two types of wireless communication networks,
