Real time spectrum sensing with certain accuracy plays a key role in cognitive radio. In this paper Cyclostationary feature spectrum sensing technique is discussed. Cyclostationary feature can be used for spectrum sensing in a very low SNR environment (less than -20 dB). The sensing algorithms are based on measurement of cyclic properties of the received signals. Usually, cyclostationary feature detection requires high computation complexity.
