Abstract

Spectrum sensing is a primary requirement in cognitive radio systems. In order to improve the spectrum efficiency and facilitate the unlicensed mobile users to use the empty licensed radio frequency band of the electromagnetic spectrum, the spectrum sensing techniques should be more accurate and reliable. In this paper, the disadvantages of basic transmitter detection techniques are discussed, and an innovative, dynamic-double-threshold energy detection scheme is proposed, which overcome the lacunas of existing techniques. Simulation analysis and results show the comparison and performance improvement in terms of detection probability and false alarm probability.
