Abstract

Efficient power control is of great importance in the design of high capacity cellular radio systems. An optimum power control scheme, in the sense that it minimizes the outage probability, has been fully investigated for FDMA/TDMA cellular systems. In this paper, the optimum power control and several centralized power control algorithms are proposed for CDMA cellular systems. Simulation results indicate that the optimum power control scheme outperforms the perfect average power control algorithm by approximately 1.9 dB under IS-95 defined radio condition
