综合业务SCDMA-HFC系统上行容量分析

Analysis of the Upstream Capacity of SCDMA-HFC System with Integrated Traffic

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。

The HFC bi-directional transmission system based on the synchronous CDMA(SCDMA) is a new generationof HFC system for transmitting the integrated traffic. In this paper, the architecture of an HFC system based on SCDMA isintroduced. The upstream capacity of SCDMA-HFC system with integrated traffic is analyzed, and the impacts of manyparameters on the upstream capacity are compared.
