In this paper, we have presented different threshold computation schemes for spectrum sensing using Fixed threshold (FT), Dynamic threshold (DT), Neyman-Pearson (NP) and Bayesian detection (BD) approach for energy detection technique. Further, we have analyzed the effect of different threshold selection approaches on the spectrum sensing performance parameters. We have also analyzed the effect of prior probability of occupancy of channel over different sensing performance parameters in BD approach.
