Abstract :
The issue of power control (PC) in the downlink of a cellular CDMA network is studied. Two approaches are discernible. The first uses the base-to-mobile-distance in order to allocate transmitted powers while the other is based on closed-loop control. The best achievable performance of a PC is evaluated for the downlink of a CDMA network. This paper then studies an almost optimal downlink power control. Numerical examples are presented in order to discuss the downlink PC performance
