Performance Analysis of Fading Channels on Cooperative Mode Spectrum Sensing Technique for Cognitive Radio

Spectrum sensing is the main feature of cognitive radio technology. Spectrum sensing gives an idea of detecting the presence of the primary users in a licensed spectrum. The sensing of radio spectrum is an essential problem in cognitive radio CR networks, where secondary users SUs need to detect the presence of primary users PUs before they use the spectrum allocated to PUs. The detection of primary user status and the spectrum sensing are the major issues in cognitive radio systems. We employ one of the simplest and most efficient Spectrum Sensing technique, the cooperative spectrum sensing with three different digital modulation techniques BPSK, QPSK, 16 QAM. In this paper, we analyze the performance of the cooperative spectrum sensing technique with BPSK, QPSK, 16 QAM modulation techniques over Rayleigh fading Channel. Further, we analyze the performance and BER Bit Error Rate of cooperative spectrum sensing under Rayleigh fading and AWGN channels. The investigation and analysis on cooperative spectrum sensing with above digital modulation techniques can be utilized for future reference of spectrum sensing in the CR networks over AWGN and Rayleigh fading channels.
