Title
Joint precoding and antenna selection for large-scale MU-MIMO uplink systems
Abstract
This paper considers the uplink of multiuser multiple-input multiple-output (MU-MIMO) systems, where, several mobile stations (MSs) cooperatively transmit hybrid messages, including common messages and private messages, to a single base station (BS). We aim to jointly design transmit precoding at the MSs side and antenna selection at the BS side to maximize the achievable system throughput. The problem at hand is nonconvex and difficult to solve mainly due to the antenna selection constraint. By exploiting the problem structure and linear relaxation, we propose using Frank-Wolfe (FW) method and the well-known weighted mean-square error minimization (WMMSE) approach to tackle the problem, leading to an efficient iterative algorithm. The convergence performance of the proposed algorithm is analyzed and its effectiveness is verified by numerical examples in terms of the achieved system throughput.
