Abstract :
A distributed multi-step power control algorithm is proposed for cellular networks. The proposed scheme utilizes local information to feedback control command for power adjustment. The sufficient condition that ensures system stability is obtained. In addition, general formula for the bound of received CIR is derived in the presence of short-term fading. The bound of received CIR is shown to be a function of number of power control steps, step size, and dead factor. Simulation results are obtained to verify the theoretical derivations
