Abstract
In a cognitive radio network, cooperative spectrum sensing can improve the accuracy of spectrum sensing and alleviate the hidden terminal problem. Cooperative spectrum sensing frame has three phases: sensing phase, cooperation phase and transmission phase. In this paper, we investigate the problem of designing the power and number of cooperative node (CN) in the cooperation phase to maximize the average throughput for secondary user (SU), under the constraint that the total cooperation and transmission power is fixed. Then, we investigate the optimal CN power or number when CN power, which yield to the maximum average throughput for SU.
