Abstract

This paper describes a cooperative sensing method implemented on software defined radio platforms USRP (Universal Software Radio Peripheral). Each node of the radio network realizes spectrum sensing with a multichannel energy detector. A WOLA (Weighted Overlap-Add) filterbank is used to split input wideband signal into set of subchannels, with energy detections performed afterwards. Sensing data from each node are sent to master node (Cluster Head) via commercial network. Based on received data, CH creates a matrix of channels occupancy and list of backup channels potentially available for own transmission.
