| 摘 要： | 出于网络优化的目的，在对PHS网络进行频率规划的前提下，分析了同频干扰对于PHS系统容量的影响，得出了PHS网络在干扰容限的限制下最小小区半径随传播条件的波动范围。通过自己搭建的PHS系统仿真平台进行了仿真验证，证明了理论分析与仿真结果的一致性，并且估算了在此结果上的PHS网络Erlang容量，提出了一些建议。

| Abstract: | For the purpose of network optimising, this paper first theoretically analyzes the influence of self - interference on the network capacity under the premise of static frequency allocation, and deducts a fluctuated range for minimum cell radius according to propagation conditions. Then the authors validate the theoretical results with computer simulation, which is programmed by ourselves. The simulation results are consistent with the theoretical conclusion. Finally we estimate the network Erlang capacity based on the conclusions, and propose some suggestions. |
