In the study in [1], a novel spectrum sensing scheme has been proposed and the performance characteristics of the proposed scheme have been analyzed in Gaussian noise environment. The test statistic of the proposed scheme is the sum of one or more order statistics of the log-likelihood ratios obtained at the branches of a receiver. In this paper, the performance characteristics of the proposed scheme are addressed in impulsive noise environment. It is demonstrated that the proposed scheme provides significant performance gain and higher level of performance stability over the conventional schemes in non-Gaussian impulsive noise environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
