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.
