Abstract:

In cognitive radio systems, a cooperative spectrum sensing method is proposed, which takes into account the relationship between control channel burden and the performance of detectors. By taking out the signals with less amount of information and quantizing the signal with more information, the accuracy of spectrum sensing and cost of the control channel are compromised in this approach.
