Abstract
In order to improve the detection performance of double-threshold cooperative spectrum sensing scheme (DCSS), we provide an improved double-threshold cooperative spectrum sensing algorithm (IDCSS). Differing from DCSS, IDCSS doesn’t always need all CR users send their local sensing message to FC. In IDCSS, fusion center (FC) successively merges the sensing results from each Cognitive Radio (CR) user and meanwhile makes the decision that whether the primary user (PU) is present or not depending on current-received sensing results. Once FC can determine that PU is present, it will broadcast this message to all CR users. Then those users which still wait for sending their sensing results will stop the sending behavior. Otherwise, FC receives and merges the next CR user’s sensing result continuously. Simulation results show that the IDCSS can achieve better detection performance with smaller data overhead than the DCSS.
