Blind multiband spectrum sensing scheme by combining model order selection with clustering analysis Open
This letter presents a robust blind multiband detection (BMD) scheme for cognitive radio (CR). In the proposed scheme, the BMD problem is firstly transformed into a model order selection (MOS) problem, and then an effective clustering meth…

Adaptive Algorithms for Bayesian Spectrum Sensing Based on Markov Model Open
Spectrum sensing (SS) is one of the fundamental tasks for cognitive radio.In SS, decisions can be made via comparing the test statistics with a threshold.Conventional adaptive algorithms for SS usually adjust their thresholds according to …

Fast Cooperative Energy Detection under Accuracy Constraints in Cognitive Radio Networks Open
Cooperative energy detection (CED) is a key technique to identify the spectrum holes in cognitive radio networks. Previous study on this technique mainly aims at improving the detection accuracy, while paying little attention to the perfor…
