| Abstract: | Synchronous CDMA (S-CDMA) solves the noise and the capacity problems of the upstream channel of the HFC system. The S-CDMA based HFC is the new generation of the HFC system. In view of the implementation of the system, non-ideal power control will cut down the service capacity of the system obviously. In this paper, an S-CDMA-HFC system model and the overview of the upstream channel are briefly introduced. The impact of the imperfect power control on the Erlang capacity of the upstream channel for the S-CDMA-HFC system is analyzed. Numerical results and are given. |
