Abstract Maximize signal-to-leakage ratio strategy is proposed in multi-user multi input multi output system, which is used to design MU-VBLAST downlink. The performance of the strategy proposed in the paper exceeds that of Block Diagonalization (BD) method which is paid wide attention in MU-MIMO systems; otherwise, the MSLNR strategy is found to relax the condition on the number of transmit-receive antennas in comparison to BD method. Simulation results illustrate the resulting system performance.
