Transmitter power control has been proven to be an efficient method to solve co-channel interference in CDMA system, and to increase the capacity of systems. A novel distributed power control algorithm based on estimates of channel gains is presented in this paper. The proposed algorithm is robust and does not require the exact knowledge of channel gains. In the proposed scheme, power control problem is converted into the zero point problem of a certain function. It is proved that the algorithm converges to the average optimal solution by stochastic approximation approach.
