基于同步码分多址（SCDMA）的HFC双向传输系统是新一代HFC网络传输综合业务的系统。本文简单介绍了一种基于SCDMA的HFC双向传输系统的结构，分析了传输综合业务的SCDMA－HFC系统上行信道的容量，比较了各种参数对上行容量的影响。
HFC bidirectional transmission system based on synchronous code division multiple access (SCDMA) is a new generation of HFC network transmission integrated services system. This paper briefly introduces the structure of a HFC two-way transmission system based on SCDMA, analyzes the capacity of the uplink channel of the SCDMA-HFC system transmitting the integrated service, and compares the impact of various parameters on the uplink capacity.
