Joint transceiver design for iterative MUD

In this paper linear precoders for non-cooperative transmitters and iterative multiuser detectors (MUD) for the receiver are jointly designed to achieve the individual quality-of-service (QoS). An evolutional analysis framework is first developed for predicting and tracking the performance evolution for each user along iterations. This semi-analytical tool then leads to a joint QoS and quality-of-convergence (QoC) constrained precoder design problem formulation that is complicated and non-convex. Due to the competitive nature of a multiaccess system, a game-theoretic reformulation is adopted to reveal the underlying partial convexity structure of the problem, which further facilitates the development of an efficient iterative solver for the problem. Extensive simulation results are given to support the mathematical development of the problem.
