为了解决广电网络的双向改造问题,规范上行回传通道标准,总结传通道设计基本原则,简化固定功率法双向HF回传调试方法,使用通道增益法固定链路增益,实现双向HFC网络回传通道的设计。 In order to solve the problem of two-way reconstruction of broadcasting network, regulate the standard of uplink return channel, summarize the basic principle of channel design, simplify the bidirectional HF return method of fixed power method, use the channel gain method to fix the gain of the link to realize the bidirectional HFC network return channel the design of.
