... component of the emerging cognitive radio networks. In this article, we study the spectrum sensing problem jointly taking the fad- ing and the location of SUs into account. We obtain the overall average ... Consequently, the spectrum sensing with jointly taking the fading and location of SUs into account is more suitable for the small scale network. Concluding remarks Spectrum...
