| 摘 要： | 首先建立了包含快衰落、阴影衰落和路径损耗的复合衰落信道模型,对分布式天线采用覆盖式（BT）传输策略,推导出给定移动台位置的小区下行点对点链路误符号率表达式.并在高信噪比条件下,通过给出移动台在小区的任意分布图,推导出小区下行平均误符号率的近似闭合表达式.仿真结果表明,所推导的近似表达式可很好地反应系统的实际性能.

| Abstract: | The article presents the average symbol error rate for distributed MIMO antenna systems in a circular area.Firstly,it establishes a composite channel model which includes fast fading,shadow fading and path loss.Then,distributed antenna cover transmission strategy is emploied,by giving the mobile station＇s location,it deduces the point-to-point downlink symbol error rate theory expression at high SNR.Finally,considering the mobile station arbitrary distribution characteristics in the neighborhood,it further deduces the average symbol error rate closed approximate expression.The simulation results show that the theoretical expression can accurately react the actual system performance. |
