摘要
3G网络的数据业务主要发生在室内,深度覆盖是当前运营商亟待解决的问题。文章介绍了一种采用数字回声消除技术的微型干扰消除直放站,它采用一体化设计,将施主天线和重发天线集成到其中,用户无需进行额外的布线和装配天线,方便安装。实际应用表明:该直放站是一种解决因建筑物导致的信号衰减和信号盲区等室内深度覆盖问题的经济、快速的解决方案。
The 3G data services mainly occur in the building interior and in-depth indoor coverage is a problem demanding prompt solution from the operators.This paper introduces a micro interference cancellation repeater using the digital echo cancellation technology.In an all-in-one design,in which the donor antenna and the service antenna are integrated in one body,removing the need for extra cable and antenna installation and realizing a real plug-and-play capability,it provides an economical and rapid solution to such problems as signal attenuation and blind zones caused by buildings.
