Wide-band cooperative spectrum sensing method

This paper describes a cooperative spectrum sensing method for a cognitive radio that is attempting to opportunistically access a wide-band licensed spectrum. This cognitive system is capable of allocating sensor nodes, which are likely to produce correlated signal measurements, to different narrow frequency bands. The cognitive radio system has therefore means of dividing the wide operating frequency band into narrow bands, and it also has the ability of clustering the sensor nodes into a plurality of clusters, so that sensor nodes that are likely to produce correlated signal measurements belong to the same cluster and so that sensor nodes that are unlikely to produce correlated signal measurements belong to different clusters.
