This paper presents a study of switching algorithm performances when combined to several beamforming techniques in a multi-user MIMO communication system. The study of three beamforming solutions shows that the beamforming processing has an important influence in the decision criterion of the switching algorithm. The STBC adaptive beamforming, which is better than Zero forcing (ZF) and Singular Value Decomposition (SVD) processing, leads to satisfactory improvement in Bit error Rate (BER) in comparison with MIMO diversity and spatial multiplexing when applied separately.
