he concept of Cognitive radio (CR) is considered as a promising solution for efficient spectrum utilization to solve the spectrum scarcity problem. This paper proposes Pattern Search (PS) algorithm for maximization of the total throughput of the communication system and increases the Quality-of-Service (QoS) of the Secondary Users (SUs) with saving QoS of the Primary Users (PUs). Moreover, a comparison between the proposed algorithm and other algorithms will be drawn. Further, the effect of the number of Primary Users (PUs), the number of Secondary Users (SUs) and the number of subcarriers are studied for increasing the total throughput for the SUs.
