Özet
Detection of primary services is important for the access of unlicensed/secondary services to TV bands in order to increase spectral efficiency. We proposed a weak wireless microphone signal detector based on higher-order spectral (bispectral) analysis. In order to reduce complexity, we estimated the bispectrum through the use of direct method and detection is performed over principal domain. Besides, probability of false alarm is derived for the proposed detector and its performance is investigated in various scenarios. © 2011 ACM. © 2019 Elsevier B.V., All rights reserved.
