For down-link communication in a DS/CDMA cellular mobile radio system, the transmitted power of the base station must be effectively adjusted in real-time fashion to achieve good communication quality because the system exists multipath short-term fading and near-far problem. In this paper, we propose two down-link power control mechanisms: one is the centralized SIR-balancing method and the other is the distributed SIR-based method. We investigate how the outage probability is affected by system parameters and optimally design the parameters for these two down-link power control mechanisms. Also, the two down-link power control mechanisms are compared and discussed.
