Goodness‐of‐fit testing is a promising approach for blind spectrum sensing in cognitive radio applications. A modification on the Anderson–Darling detector by taking into account the physical characteristics of spectrum sensing is presented, resulting in a reduction of the false alarm rate by a factor of two for a given detection threshold in the binary hypothesis test.
