异扇区同PN(伪噪声)码,即不同扇区使用相同的PN码模式,是指把物理上原本两个或两个以上扇区,合并成一个逻辑上的大扇区,也就是某个区域原来存在几个不同PN信号,现在合并成一个PN信号进行覆盖。异扇区同PN模式应用于话务不甚高的区域,具有光纤直放站所有优点,很好地扩大了覆盖范围,性能又比光纤直放站优越得多,与传统PN模式相比具备很多优点。对同PN RRU(射频拉远单元)现网场景使用方案提出了建议。
Different sector with PN (pseudo-noise) code, that is, different sectors use the same PN code mode, refers to the physical two or more original sector merged into a large logical sector, which is a There were several different PN signals originally in the area, which are now combined into one PN signal for coverage. Different sector with the PN mode is applied to the traffic is not very high area, with all the advantages of optical repeater, a good expansion of the coverage, performance and optical repeater is much better than traditional PN mode Many advantages. Suggests the usage scenario of the current network scenario with the PN RRU (Radio Remote Unit).
