无线直放站应用中的干扰分析与解决方法

Interference and the Solution in Application of Wireless Repeater

无线直放站的应用会给移动通信网络带来一些干扰问题,如导频污染、直放站自激、上行噪声对基站的干扰、前端饱和引起的阻塞干扰和对邻近小区的影响等。本文对这些干扰的机理进行技术分析,并提出了减少和避免各种干扰的方法。应用这些分析和方法,就能扬长避短,最大限度地发挥无线直放站的优势。

The application of the wireless repeater will bring some interference problems to mobile communication network,such as pollution of pilot frequency,self-excited of repeater,interference of Up-stream noise,man-made noise caused by front saturated and impact on nearby village and so on. This paper analyzes the mechanism of these interference,and puts forward methods to avoid and reduce interference,so that it can foster strengths and circumvent weaknesses.
