利用随机逼近方法研究随机功率控制问题 ,将功率控制问题转化为寻求一个不确定函数零点的一个随机逼近问题。在承认随机噪声时 ,证明了所提出的算法在均方差意义下收敛到最优解 The stochastic approximation method is used to study the problem of stochastic power control, which transforms the problem of power control into a stochastic approximation problem for finding a zero point of uncertain function. When admitting the random noise, it is proved that the proposed algorithm converges to the optimal solution under mean square error
