WCDMA与其他系统共址时隔离度的计算

Calculation of Isolation between WCDMA and Other Systems When Their BTS Are Co-located

本文首先分析了不同系统间的主要干扰类型,并详细阐明了各种干扰的数学计算方法,然后提出了解决这些干扰的隔离要求,并阐明了理由,最后根据各种系统的规范要求对WCDMA与GSM、CDMA、PHS、TD-SCDMA相互之间的干扰情况进行了分析,得出了WCDMA与其他系统共址时所需的隔离度及天线隔离要求。

In this article, we analyse the major interference among different systems, and expound the mathematic methos of various kinds of interferences at first. Then, we present the essential requirement of isolation for solving these interferences and expound the reasons. At last we analyse the interference cases, and propose the isolation request and antenna isolation request between WCDMA and others systems when their BTS are Co-location.
