Abstract

Abstract

In order to reduce effect of hidden terminal on cognitive system performance and the error rate of perceived system, it is proposed that, under the condition of considering wireless Rayleigh fading channel and reported channel with a fixed error probability, joint optimize index p of p power detector, optimal sensing threshold and the best number of cooperative users K on multiple antenna sensing system with p power detector to minimize the total error probability. Theoretical analysis and simulation results show that cooperative spectrum sensing system has the best index p* and the best perception threshold *, and when choosing a fusion rule it can improve the reliability for sensing system by choosing appropriate cooperative users K.
