| 摘 要： | 引入空间排队(spatial queues)理论,用空间位相型到达过程(SPHAP)描述无线小区中来自不同服务区域到达过程的空间结构,从而建立了基于不同服务区域的无线通信网络的业务接入模型,即SPHAP/M/c/c损失系统。推导出了无线通信空间性能指标,用于系统在无线空间结构上的分析和设计,并且给出了优化策略,通过系统仿真得到了优化结果。

| Abstract: | By introduced spatial queues theory,a SPHAP/M/c/c loss system was brought forward to model the admit process of traffic form different service area,using spatial phase type arrival process describe the spatial structure of the traffic from different sectors in the same zone.The exact spatial performance measure such as channel utilization ratio of the system and the sectors,blocking probability of the system and the sectors is got.And these can be used to analysis and design the spatial structure of the system.A strategy is designed to optimize the system,and via system simulation is got the optimization results. |
