Figure 7From: On the user performance of orthogonal projection signal alignment scheme in MIMO relay systemsErgodic sum rate for eOP-SI with different relay antennas. Figure7 provides the ergodic sum rate with different relay antennas numbers, where the number of relay antennas are fixed as N=3,4,5, respectively. The simulation results show that the ergodic sum rate of eOP-SI scheme raises with the increment of the relay antennas.Back to article page
