An improved spectrum sensing method based on multitaper-singular value decomposition in Cognitive radio

Abstract

In order to improve the spectrum hole detection in Cognitive radio (CR), Multitaper Method with Singular Value Decomposition (MTM-SVD) has been proposed. However, how to decide the coefficient in the spatiotemporal complex matrix constructed by MTM-SVD is still under discussion. In this paper, a new scheme, employing array signal processing, for coefficient… (More)
