... for the ZF beamformer with N t = 3of2 ×(3-1)=4,andthis is equivalent to that of the SU transmit-MRC scheme with four transmit antennas. Similarly, the ZF beam- formin g scheme with N t = 2 provides ... SU scheme with two transmit antennas. The figure also shows that the SNR gain of the ZF beamforming scheme with N t = 2 is of approxi- mately 0.5 dB less than that of the SU...
