Abstract :
This paper obtains a new centralized stochastic power control algorithm for a DS/CDMA single cell uplink environment where the channel fading process is modeled by a stationary finite state Markov chain. Constrained stochastic approximation methods can be used to solve the stochastic optimization problem.
