Intensive simulations show that fading degrades the average sensing accuracy for an optimally adjusted carrier sensing threshold.
where m is the Nakagami fading parameter, which measures the amount of fading, [bar.[gamma]] is the average received SNR, and [GAMMA](.) is the gamma function.
The variation of combined cdf and pdf against the instantaneous SNR are shown in Figures 1-4 (four combinations of fading) taking average SNR (absolute) of the 1st hop and the 2nd hop as a parameter.
In [13] performance analysis of cognitive amplify-and-forward relaying with best relay selection strategy is considered when non-identical Rayleigh fading channel is assumed.
Parameter [mu]>0 is defined as [mu] = [E.sup.2][[r.sup.2]] / 2V[[r.sup.2]] (1 + [(H /h).sup.2]) where E[.] and V[.] denote the operators of mathematical expectation and variance, and r is the fading envelope.
