Comparison of the achievable transmit rates with the BB algorithm, the heuristic algorithm, and the reference algorithm. Figure 5 illustrates the maximum achievable transmit rate for the SU using the BB algorithm in comparison with the heuristic algorithm and a reference algorithm from [9–11]. The outage probability limits, pth, are set as 0.21 and 0.31, respectively. The parameter values for c in the reference algorithm are set to 0.7 and 0.5, which leads to outage probabilities of 0.21 and 0.31, respectively.
