Abstract

In this paper, a number of spectrum sensing schemes implementation in ultra wideband and Cognitive radio component (UWB-CR) under different fading settings condition are studied. The sensing performance of different detectors is compared in conditions of probability of miss detection curves. Numerically simulation results are shown that the selection of detector rely on the scenario, the detector requirements and on the obtainable prior knowledge. Also simulation results can be shown that it is possible to achieve better detection performance in choosing frequency channel by exploiting the autocorrelation in cyclostationary detection algorithm.
