Cooperative cognitive network: Performance analysis of Cyclostationary spectrum detection

The Cognitive Radio (CR) continuously monitors the spectrum to detect the presence or absence of the primary user. Cyclostationary is one the efficient spectrum sensing method as it can differentiate among signal, interference and noise in low SNR. In this paper we illustrate the cooperation in cognitive radios by using the Cyclostationary sensing method. We consider the case of cognitive radio cooperating through AWGN channel and using both Amplify-and-Forward (AF) and decode-and-forward (DF) Relaying schemes with different relay locations and exploit their probability of detection. Here we generalize our analysis to two-relay based cognitive radio network for Monte Carlo simulation.
