Uplink communication in a cellular radio network is considered where the base station in each cell employs linear or decision feedback multiuser receivers. We address the problem of minimizing the total of the user transmit powers over all linear or decision feedback multiuser receivers, such that all the users achieve their signal-to-interference ratio (SIR) targets. A distributed algorithm is obtained that is shown to converge, both in the deterministic and stochastic formulations, to the jointly optimal pair of power allocations and multiuser receivers.
