Performance of wideband spectrum sensing under fading channel

In this paper, we study the performance of the wideband spectrum sensing for cognitive radio network under different fading channels. We compare the performance of wideband spectrum sensing where each channel in the band undergoes fading with that of additive white Gaussian noise channel. We used probability of excessive interference opportunity and probability of insufficient spectrum opportunity as the performance measure. Partial band Nyquist sampling is considered as the wideband sampling scheme throughout the paper. The effect of different parameters on the performance of the system is analyzed.
