USRP setup for energy detection-based Cooperative Spectrum Sensing for Cognitive Radio Networks
Maršálek Roman, prof. Ing., Ph.D., UREL (FEEC)
The cognitive radio technology allows solving one of the main issues of current wireless communication technologies, namely a deficit of vacant spectrum. A dynamic spectrum access used in the cognitive radio networks (CRN) gives an ability to access to an unused spectrum in real time. Cooperative spectrum sensing is the most effective method for spectrum holes detecting. It combines sensing information of multiple cognitive radio users. The aim of this paper is to present the experiments with the cooperative spectrum sensing making use of the two USRP 2 software defined radio devices
In this work we present a setup for the evaluation of the cooperative spectrum sensing using the Universal Software Radio Peripheral (USRP) devices synchronized through a MIMO cable and with further processing in the GNU Radio and Matlab software. The paper presents first results of evaluation of the several cooperative schemes on the IEEE 802.22 – like signals gathered with this setup.
