HFC上行信道噪声干扰解决方案

Study on the Noise Interference Problem of the Upstream Channel in HFC

文中深入研究了HFC宽带综合业务网上行信道中的噪声干扰问题。分析了噪声干扰模型、噪声干扰的类型、来源和噪声漏斗效应。通过提取常见内部噪声、外部噪声的案例及产生的数据,对HFC有线电视宽带综合信息网中上下行数据传输质量进行了讨论,提出以隔离为主要思路的新型HFC宽带综合信息接入系统,同时论述了系统的结构和方案的可行性。

This paper giving some analysis and study on the noise interference problem of the upstream channel in CATV broadband integrated service network. It analyze the noise interference in the upstream channel and its effect on the network.A new HFC broadband access system is proposed. It discusse on downlink data transmission quality of HFC CATV broadband integrated information network, The main idea of the model is to isolate the HFC broadband integrated information access system, and discusse the feasibility of the structure and scheme of the system.
