Wideband spectrum sensing technique based on Goodness-of-Fit testing

Recently, Goodness-of-Fit (GoF) based spectrum sensing has been proposed as a method for blind narrowband spectrum sensing. GoF based spectrum sensing has the nice feature that, compared to Energy Detection, it needs fewer samples to achieve the same sensing performance. In this paper, we present how GoF based spectrum sensing can be integrated in a conventional wideband spectrum sensing scheme, resulting in an accurate technique with a very short sensing time, which makes this method attractive for cognitive radio applications.
