Multitaper Based Spectrum Sensing for Cognitive Radio: Design and Performance

Using the multitaper spectrum (MTS) for spectrum sensing in cognitive radio has been investigated by a number of researchers. An MTS detector can be applied to various operational environments with the knowledge of perfect or inaccurate noise variance. So far, however, no systematic procedure is available for the determination of theoretical thresholds and their corresponding detection performance. In this paper, we tackle this issue, ending up with various closed-form analytic formulas for the probabilities of detection and false alarm with different settings. The validity of theoretical formulas are examined intensively through numerical results and computer simulations.
