Joint time-frequency spectrum sensing for Cognitive Radio

Abstract : In this paper, we propose a new concept of spectrum sensing techniques based on a joint time-frequency detection of primary users. In this new approach, we aim at detecting the presence of the PU in frequency and in time as well. The proposed technique based on an algebraic detection of the spectrum is compared to one of the most well known tool in time frequency analysis tools: the Wigner Ville Distribution. Simulation results show how reliable the proposed technique is comparing to classical energy detection in time-frequency plane.
