Abstract: Despite its simplicity, the zero-forcing receiver is known to suffer from noise enhancement to restore the spatially multiplexed data in a point-to-point MIMO system. Nevertheless, in the point-to-multipoint multiuser system, the poor channel avoidance property of the scheduling technique provides a natural way to overcome the drawback of noise enhancement. In this paper, we present an analytical framework to evaluate the performance of the zero-forcing receiver operating in the multiuser MIMO system with scalar feedback scheduling. Using the order statistics technique, we derive closed-form expressions for the achievable throughput of the zero-forcing receiver operating in the multiuser MIMO environment. Our analytical results indicate that the cross-layer cooperation of the simple zero-forcing receiver and scheduling technique can achieve the full capacity of the point-to-point MIMO system.
