【Abstract】 This paper focus on developing a novel distributed power control algorithm based on stochastic approximation approach. The optimal control is first converted into one stochastic approximation problem that seeks for the zero point of one uncertain function. Then the distributed power control algorithm is derived in a simple way. The presented iterative power is updated by using its own channel gain. Further, in case of admitting the stochastic noise. It is proved that the algorithm converge to the optimal solution in sense of mean-squared.更多还原
