From: A new mathematical analysis of the probability of detection in cognitive radio over fading channels
Probability of detection vs SNR for BPSK signal. With fs = 10f c , P fa  = 0.01, and different odd with N =31 , even with N = 32 number of degrees of freedom. In the odd case, the simulation is compared to the recursive formula (13,16) in AWGC, and in the even case, the simulation is compared to (10) in AWGC and to ([14], Eq. 14).
