Fig. 9From: EQSM-based multiuser MIMO downlink transmission for correlated fading channelsBER performance comparison for an (4·4)×16 configuration and a correlated fading channel. This figure compares the three proposed MU-MIMO-EQSM schemes with the conventional ones considering a spectral efficiency of 12 bpcu for all systems and a spatial correlated channel with Tx antennas separated by 1.5 λBack to article page
