Abstract

In this paper, a system of centralized cooperative spectrum sensing is designed. Energy detection and cyclostationary feature detection are used by Secondary User. The stepping spectrum sensing function is used to sense and record the vacant spectrum around the location of SU and then the information is uploaded to the control center with its coordinate. This system can make a pre-judgment for SU based on the uploaded information. And when have SU need to make a communication, the SU can find the vacant spectrum fast depending on the data fusion. In this system, we use NI-USRP2920, USRP1 as the hardware platform and GNU Radio, LabVIEW and HDSDR as the software platform.
