抑制HFC网上行通道干扰噪声的方法

摘要

目前，HFC网络上已广泛应用于广电双向数据业务，而有效抑制和降低双向网络中上行通道的干扰噪声问题是建设一张优质网络的关键。本文在分析了HFC网络的上行通道噪声产生原因的基础上，提出了几种抑制上行通道干扰噪声的方法。%At present,the HFC network has been widely used in radio and television two-way data business,and effectively restrain the two-way network and reduce the upstream path noise interference is building a network of high quality key.Based on the analysis of HFC network of causes of the uplink channel noise are put forward,based on the uplink channel noise interference several inhibition of the method.
