Spectrum sensing is a vital cognitive radio function that protects licensed users from dangerous interference and finds accessible spectrum for better spectrum use. In practice, however, multipath fading, shadowing, and receiver uncertainty frequently degrade detection performance. Communication performance and continuity in cognitive radio networks are heavily dependent on how well the spectrum sensing function is implemented. The significance of selecting the right wavelet system is discussed.
