摘      要：For reducing the inter-user interference in multi-user multiple-input multiple-output（MU-MIMO） wireless communication systems,e.g.,MIMO-orthogonal frequency division multiplexing（MIMO-OFDM） systems,it is often desirable to the complex preprocessing at the *** paper proposes a multi-user beamforming algorithm with sub-codebook *** on the minimal leakage criterion,the codebook selection,limited feed-forward and minimum mean square error（MMSE） detection are combined in the proposed *** avoids the complex channel matrix decomposition and ***,the computational complexity at the transmitter is significantly *** results show that the proposed algorithm performs better than existing beamforming algorithms.
