We consider the problem of joint admission control and resource allocation in a secondary code-division network coexisting with a narrow-band primary system. Our objective is to find the maximum number of admitted secondary links and then find the optimal transmitting powers and code sequences of those secondary links such that the total energy consumption of the secondary network is minimized subject...
We consider the problem of joint admission control and power allocation in a multiband cognitive radio network (CRN) coexisting with multiple narrowband primary systems, and investigate two separate optimization problems: i) sum-rate maximization under primary user (PU) and secondary user (SU) quality of service (QoS) constraints; ii) sum-rate maximization and power minimization under PU and SU QoS...
