Abstract
In this paper, we propose a novel linear beamforming scheme for multiuser two-way MIMO relay channels to maximize the system sum rate. To achieve a low complexity, our scheme is designed by using the non-iterative method based on generalized channel inversion (GCI). Both perfect and imperfect channel estimations are considered in the design. Simulation results shown that the proposed scheme outperforms the existing scheme in the scenarios with or without channel estimation error.
