摘要：A cognitive radio system is provided comprising a master node and a plurality ofmobile terminals. The master node comprises receiving means for receiving, from aplurality of sensor nodes, detection information indicating whether or not the sensornode has sensed a primary user transmission; obtaining means for obtaining, for eachsensor node, a measure of a signal to noise ratio, SNR, of secondary user signals receivedat the sensor node; checking means for checking reliability of the detection informationreceived from the plurality of sensor nodes using the obtained SNR measure for thecorresponding sensor node; and decision means for deciding if a primary user istransmitting using a subset of the received detection information that has been
determined to be reliable by said checking means. By reliably detecting primary users ofa frequency band, secondary users are able to utilize the band when the primary user isnot transmitting or receiving.
