Abstract :
Spectrum sensing is regarded as an important part of the CR network. Its detection accuracy is the key aspect which affects the performance of CR network. In this paper, a novel cooperative spectrum sensing based on radio environment map (REM) is proposed. This new algorithm utilizes the REM information of the primary users (PUs) and the secondary users (SUs) to raise the detective performance of the spectrum sensing. Simulations show that the detection accuracy is improved and this algorithm is more suitable for practice wireless channel because it needs no priori information of SNR.
