Minimizing the coarse-fine spectrum sensing time of cognitive radios with ideal secondary detectors subject to noise uncertainty
Brendan Lawton, Colin C. Murphy · 2011
In previous work a method was derived for generating estimates of design curves for Coarse-Fine spectrum sensing. One of the problems that the method had was it could not account for variations in noise power. If the noise was uncertain or not the same across the bands, then the model could not predict the performance correctly.
