| Summary: | Cognitive Radio (CR) is an intelligent system for
opportunistically accessing the idle resources and a solution for
spectrum resources scarcity. The main purpose of this article is to
analyze the performance of Energy Detection under Nakagami
and Rayleigh fading channels and compare it with the case of when
there is only AWGN. Probability of detection and probability of
false alarm are used to characterize the performance of the energy
detector under different received SNR. It was found that energy
detection has better detection performance when there is only
noise and this performance deteriorates with the introduction of
Nakgami fading. The worst performance was in the case of
Rayleigh fading. This clearly shows that the performance of the
energy detector is worse in fading channels and further
deteriorates with the severity of the fading.
