(RCRNs) system models discussed in literature for UL spectrum access and provide a study …

… pair of cognitive transceiver nodes, where multiple DF relays are … by a set of relays, a joint
relay selection and power allocation … A suboptimal RA algorithm for a DF relay CR network is …

… Two main relay selection techniques have been introduced … : opportunistic relay selection
(ORS) and partial relay selection (… –relays–destination are required for choosing the best relay. …

… combination of relay selection criterion and signal-combining technique in cognitive radio
networks because proactive relay selection is the outageoptimal relay selection criterion and …

… For cognitive radio transmissions to be successful, we assume that the primary users are
collaborative and are able, somehow, to provide the secondary users with interference …

… and relay selection. The interference management for cognitive wireless networks is also …
Then, we solve the subcarrier pairing and relay selection problem in two steps. Simulation …

… Different relay selection schemes are compared by the numerical results, and we find that
as the relay selection increases the spectral efficiency of the system, while the average BER …
