Spectrum sensing based on cyclostationary feature detection for cognitive radios with multiple antennas

Cognitive radios aim to implement dynamic frequency usage which is proposed to increase the efficiency of the spectrum and can sense their environment, detect the idle bands and then allocate the secondary users into the detected idle bands without any interference to primary users´ communications. Cyclostationary Feature Detection is one of the commonly used methods in the literature for spectrum sensing. This paper focuses on sensing the idle bands using cyclostationary feature detection method in Cognitive Radio based systems. The performance is improved by using the proposed multiple antenna technique and the simulation results are analyzed.
