Blind multiband spectrum sensing in cognitive radio network

Blind multiband spectrum sensing for cognitive radio systems with smart antennas

“…Thus far, there are a few sensing algorithms proposed in the literature. Here, we choose the MME detector [11] and the information theoretical criteria based AIC/MDL detector [14] for comparison. These algorithms require no prior knowledge of the noise power and thus are robust to the noise uncertainty.…”

“…To deal with the multiband spectrum sensing for the CR, the ED is conducted to perform a narrowband detection independently in a particular subband at a time [13]. Information theoretic criteria are applied to the spectrum sensing as a model selection problem in the frequency domain, where the decision is made at each frequency band individually [14]. Another set of information theoretic criteria‐based spectrum sensing algorithms investigate the multiband spectrum sensing in the time domain from a different perspective [15, 16].…”
