Abstract :
This paper investigates multi-carrier relay selection schemes in cognitive radio system. As the wireless spectrum resources allocated to primary users cannot be occupied all the time, there are variable available idle sub-channels left for the secondary users (the cooperative communication system in this paper). Two kinds of relay selection schemes are proposed and the system throughput is addressed and analyzed.
