An adaptive filter configuration, known as the adaptive line enhancer (ALE), was introduced by Widrow etal. [l] as a method of detecting a periodic signal in an incoherent background. Recently, Reddy el al. [2] and Egardt el al. [3] derived an optimum value for the decorrelation parameter, A, in the ALE and demonstrated with many simulations that frequency(More)
In cognitive radio networks, spectrum sensing plays a crucial role in the discovery of spectrum opportunities for secondary systems (or unlicensed systems). The performance of spectrum sensing is characterized by both accuracy and efficiency, and more importantly the time taken to make a decision and also the complexity involved in doing so. In this work we(More)
