Abstract :
According to the Federal Communication Commission, spectrum allocation will be one of the problems of future telecommunication systems. However a lot of spectrum holes can be detected in spectrum of different networks, that cognitive radio systems are responsible for detecting, and assigning them to other purposes. Cyclostationary based detection, as one of the most sensitive methods for signal detection, can be used for recognition of DVB-T2 signal. In this paper, cyclostationary features of DVB-T2 signal are investigated and a cyclostationary based algorithm for detection of this signal is presented.
