Abstract

In this paper, we proposed a vector perturbation precoding approach based on reactive tabu search (RTS) for large multiuser MIMO (MU-MIMO) systems, where ‘large’ means tens to hundreds of transmit antennas (N t ) at base station simultaneously serving almost the same number of user terminals (UTs) (N u ). By exploiting RTS, contrast to the conventional algorithm, the proposed approach can efficiently escape from poor local minima and has the relatively low complexity. Additionally, for the error bit rate (BER), this proposed approach also has the diversity increasing with N t and N u , thus making it suitable for large MU-MIMO systems both in terms of complexity and performance.
