Research to resist the noise based on HFC network

Currently,Community Antenna TeleVision networks in our country are HFC networks mostly,the access network already becomes the "bottleneck" when the users enter information superhighway.In order to implement Two-Way data and interactive composite profession's development,the crucial issue is to resolve the noise in up channel of the HFC network.The article is to introduce methods which could reduce the noise interruption and S-CDMA(synchronous division multiple access) technology in the double-way HFC network based on CATV.
