Abstract

Abstract:

Fast control channel selection algorithm for cognitive radio is proposed. Firstly, the delay caused by signal transmitting and processing is utilized to achieve fast control information exchange. Secondly, the process of spectrumhole selection is optimized, that will decrease the number of the spectrum holes used for control channel. Finally, the control channel interruption, caused by the reappearance of primary users on spectrum hole, is significantly avoided. Derivations and simulations prove the increase of the performance on the above mentioned aspects.

Key words: cognitive radio, spectrum hole, control channel, interruption ratio, signal form
