Proposed is an adaptive fully transmitter‐based block‐diagonalisation scheme for multiple input multiple output (MIMO) multiuser downlink systems. A relaxation to the beamforming optimisation constraints is proposed, which introduces interference diversity and attains a more efficient performance optimisation. The trade‐off to the performance improvement is an increase in the precoding complexity imposed by the adaptive nature of the proposed beamforming. A sub‐optimal adaptive‐decomposition beamforming scheme is also proposed with a reduced complexity overhead. Comparative analytical and simulation results to conventional beamforming demonstrate the significant diversity gains offered by the proposed scheme.
