Abstract

In this paper, the DTV (digital television) spectrum sensing problem is studied, which plays a key role in the cognitive radio. In contrast to the existing higher-order-statistics (HOS) approach, we propose a novel robust spectrum-sensing method, which is based on the JB (Jarqur-Bera) statistic. In our studies, the existing detector may often not be robust when the sample size is small. Our proposed JB detector is heuristically justified to be superior for the simulated microphone signals as well as the real DTV signals. Moreover, the computational complexity analysis for our proposed new JB detector and the HOS detector is also presented. Ultimately, the normality test and the spectral analysis are provided to justify the advantage of our proposed spectrum sensing method. © 2006 IEEE.
