Signal detection in cognitive radio networks over AWGN, Nakagami-m and Nakagami-q channels
In this paper, we consider the problem of spectrum sensing based on energy detection (ED) method in cognitive radio (CR) over wireless communication channels when users experiences fading and non fading effects. The closed form analytical expressions for the detection probability are derived over non fading Additive White Gaussian Noise (AWGN) channel and Nakagami-m and Nakagami-q fading channels. The detection probability involving Marcum-Q function is replaced by closed form expression. The probability distribution function (PDF) of fading channels is used to obtain the expressions for detection probability. The new derived numerical results are simulated under various parameters. The performance of the derived theoretical expressions closely matches with the simulated results.
