With the rapid increment in wireless applications and due to improper utilization of spectrum band, it becomes very necessary to handle spectrum scarcity problem. Cognitive radio is one of the promising solution for handling spectrum scarcity problem; as it allows unlicensed user to use licensed band by dynamic spectrum management. Spectrum sensing is an essential part of cognitive radio, which allows it to sense the spectral band to find the presence of primary user signal. There are several methods available for spectrum sensing; one of them is cyclostationary detector having better performance than other for low SNR condition. In this paper, a real-time implementation of spectrum sensing for cognitive radio is done using Universal Software Radio Peripheral (USRP) N210 kit with VERT2450 antenna is used for hardware support and Matlab®/Simulink® software tool is used for further processing of signal. A comparative analysis of cyclic spectral density has done for different modulation scheme & SNR values and BER performance is analyzed for different Eb/N0Values.
