Ergodic sum rate of OP-SI with different power constraints. In Figure3, the ergodic sum rate of OP-SI with different power constraint schemes are also plotted by Monte Carlo simulation, where M=2,4,6,N=M + 1. As shown in the figure, the ergodic sum rate curves of OP-SI with two types of power constraints are very close in high SNR region, and the performance gap is less than 0.2 Bit/s/Hz.
