摘要
The main spectrum sensing (SS) techniques suitable for cognitive radio networks (CRNs) such as energy, matched filter, covariance and Hadamard ratio-based detectors are analyzed. Principal methods and concepts associated with SS-CRNs are explored while numerical simulation experiments and comparison analysis are interpreted aiming to corroborate those concepts and demonstrate the effectiveness and drawbacks of those well-established SS-CRN techniques and methods.
