Abstract — This paper studies the convergence issue in stochastic implementation of standard power control algorithms in wireless communications. It is shown that, under a set of general assumptions, the stochastic power control algorithm converges to the componentwise smallest power vector with probability one. The results are further extended to the joint stochastic power control and receiver optimization problem. Simulation results are given to illustrate the performance of the proposed algorithms in practical systems. I.
