Optimization for Cooperative Spectrum Sensing Mechanism in Cognitive Radio System

In order to maximize the spectrum sensing efficiency in the interference-limited primary systems,this paper proposes an optimization scheme for cooperative spectrum sensing mechanism in Cognitive Radio(CR) system.It defines the system model,jointly optimizing the crucial sensing parameters of sensing duration,transmission duration and the numbers of CR users participating in cooperative spectrum sensing.Simulation results show that the proposed scheme is capable of maximizing the spectrum sensing efficiency while satisfying the interference-limited.
