Abstract

A new power control scheme for downlink CDMA transmission by using an outage probability criterion is proposed in this research. We first analyze the outage probability when data are transmitted over shadowing and Rayleigh fading channels. Then, the power is assigned to each link of the system so that the overall outage probability is minimized subject to three constraints. They are the total transmission power at the base station, the maximum transmission power for each user, and the maximum tolerable outage probability for each user. The Newton-Raphson algorithm is modified to solve the minimization problem under these constraints. Experimental results demonstrate that the proposed algorithm is capable of differentiating QoS requirements for each link in addition to improving the throughput of the system.
