摘要
系统地分析了HFC结构噪声和入侵噪声等发生的原因和特点,提出了一些解决的措施,如:做好网络的屏蔽和维护,考虑灵活的接入协议和传输技术,采用窄带FDMA、滤波、预箝位及前向纠错技术等.
HFC (Hybrid Fiber/Coax) network can be used for bi directional communication. While providing interactive services over HFC network, one of the most important performance indexes is BER. The noise upstream channel of HFC network will determine the overall reliability of the system data link. The source and characteristics of the structural, ingressive and other types of noise are analyzed, and some countermeasures are suggested.
