Abstract

^{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}.
