Efficient Cooperative Cyclostationary Spectrum Sensing in Cognitive Radios at Low SNR Regimes

This paper proposes efficient cooperative cyclostationary spectrum sensing schemes in which each secondary-user (SU) performs single-cycle (SC) cyclostationary detection for fast and simple implementation, while collaboration between SUs in final decision on the presence or absence of the primary-us...
