Efficient and reliable detection of spectrum holes is an important technology for cognitive radio.

This paper proposes a new spectrum hole detection scheme based on the cyclic-statistic according to the cyclostationarity of the primary user signal.

Analysis of energy detection based spectrum sensing in noise of uncertain power;

This paper classifies the mainly spectrum sensing algorithms according to primary transmitter detection and primary receiver detection and makes contrast of them.

In order to solve the problem of spectrum recognization in cognitive radio,the spectrum sensing methods of recent years are described.

Performance analysis of cooperative spectrum detection under correlated decision

In cognitive radio, spectrum detection is targeted on detecting the interference temperature.

This paper starts with the concept of cognitive radio, focuses on the key techniques, such as spectrum detection, spectrum management and power control, as well as the applications of cognitive radio in ultra-wide-band, Mesh network and wireless area network.
