HFC网络上行噪声控制系统

分析HFC接入网上行通道的噪声问题，并介绍一种用于上行通道噪声控制的系统，该系统能实时监控HFC网络的运行信噪比，并对入侵噪声进行及时定位和处理，较好地提高了HFC网络的通信质量。

This paper had analyzed the problem of the noise of the HFC return path, and given a intro-duction of a system controller used to control the noise of HFC return path. The system can monitor C/N of the performing HFC network, locate and process the noise in time. The quality of communication of HFC is improved.[
