Impact of Noise Power Uncertainty on Cooperative Spectrum Sensing in Cognitive Radio Systems

Abstract

One of the main challenges in cognitive radio (CR) communications lies in the system robustness to uncertainties. In this paper, we examine the impact of the noise power uncertainty on the performance of various detectors in CR networks. We consider both single and multiple CR nodes. For the single CR case, we compare the performance of the energy and… (More)
