Before revision:  The first algorithm, for instance, enables the SUs to reach 99.19\% of the throughput obtained by the optimal SM while providing an acceptable level of fairness among the SUs. The structure and performance of the proposed SM setting schemes are discussed in detail and a set of illustrative simulation results is presented to validate their performance .
