WCDMA与PHS系统共存干扰分析与解决方案

The Analysis and Solutions about PHS and WCDMA Co-exist Interference

本文结合3GPP、STD-28协议以及路测结果对WCDMA与PHS系统共存时无线环境干扰进行了理论计算分析,并利用PHS基站、手机杂散测试结果得出规避干扰需要的理论隔离度,就干扰判定方法以及滤波器安装准则进行了介绍。

This paper analyzed the wireless environment interference between PHS and WCDMA based on the protocol of3GPP and STD-28 while the field test also verified the co-exist interference. To calculate the MCL, the author measured the spurious of PHS cell - station and ceU-phone. The way to judge the interference source and the rule of installing filter to solve the co-exist interference were also introduced.
