Grouped Linear ZF Receiver for Multiple Antenna Systems

In this paper, we present a new group iterative linear zero-forcing receiver for MIMO system. The signals of all layers are firstly grouped and the signals in every group are detection by linear Zero-Forcing method. The successive interference cancellation detection is applied between the difference groups. Simulation results states the proposed algorithm achieves marked performance improvement compared to Zero-Forcing algorithm with a litter increase of computational complexity. Compared to the conventional ZF-VBLAST, proposed scheme reduces the complexity and delay greatly with a litter performance loss.
