| 摘 要： | CDMA2000系统是一个自干扰系统,网络分布为微蜂窝结构,每个基站小区都有相对确定的覆盖范围,为了避免重叠覆盖所增加的小区内部干扰,降低系统容量,必须减少信号重叠情况.CDMA网络特性不允许信号发生越区覆盖,若越区覆盖则产生很大的危害.笔者揭示越区覆盖对网络的危害,浅析如何发现建筑物高层越区覆盖现象及其解决方法.

| Abstract: | CDMA2000 system is a self-interference system according to the network distribution of micro-cellular structure.Each cell has a relative fixed coverage and signal overlapping coverage should be minimized in the planning stage.Overlapping coverage will increase the cell self-interference to reduce system capacity.CDMA network characteristic does not allow crossdistrict coverage of this situation,as the event of cross-district coverage does enormous harm.This article will elaborate how the cross-district coverage does harm to the network,how to determine the high-rise buildings covered by the signal of cross-district coverage,as well as cross-district coverage optimization method. |
