摘要 该文针对多用户MIMO系统提出利用最大信号泄漏信噪比准则设计多用户VBLAST下行链路的方法。相对于以多用户系统中广泛关注的块对角化方法设计多用户VBLAST下行链路,所提方法性能有较大的提高。另外,相对于块对角化方法对天线数目的约束,该文所提方法在不满足块对角化的条件下仍能拥有不错的性能。仿真表明该方法拥有优异的性能。 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.
