In this paper, a modified multi-step SIR-based down-link power control method is proposed. The main idea is to predict the variation of Rayleigh fading from the received signal-to-interference ratio and then to track it in time. A computer program is developed to simulate the performances of this new method as well as the original multi-step SIR-based method. Simulation results show that, of the two, the former performs better than the latter, even if the bit error rate of power control command is around 0. 001.
