First, the S-CDMA-HFC system with integrated traffic is introduced and the method of traffic integration is given. Second, the upstream channel capacity of the S-CDMA-HFC system with integrated traffic that has the same rate is analyzed. The chronoff limit and Gaussian approximate equation of the upstream channel cutoff probability are derived. Third, the impact of the selection of the line transmission rate on the upstream channel capacity of the S-CDMA-HFC system with integrated traffic is discussed in detail. The cutoff probability and throughout equations of the upstream channel with different integrated traffic are derived. Fourth, the impact of the power control error on the capacity is discussed. Results show that the power control error will degrade the upstream channel capacity and have different influence on the different traffic. Finally, the capacity requirement of the initialization process is raised. Analytical results show that the initialization process will impact on the capacity slightly.

首先，简单介绍了综合业务S-CDMA-HFC系统，给出了业务综合的方法；然后，分析了具有相同码率的综合业务条件下的S-CDMA-HFC系统上行信道容量，导出上行信道中断概率的切尔诺夫上限和高斯近似公式；然后，详细讨论了基本传输速率的选择对综合业务S-CDMA-HFC系统上行信道容量的影响，导出了不同业务综合条件下上行信道的中断概率和吞吐量公式；然后，讨论了功率控制误差对综合业务S-CDMA-HFC系统上行信道容量的影响，结果表明功率控制误差会使上行信道容量下降，且对不同业务的影响程度是不同的；最后给出了初始接入的容量要求，分析结果表明初始接入将对综合业务S-CDMA-HFC系统上行容量带来影响，但不明显。
