—Maximization of the weighted sum-rate of secondary users (SUs) possibly equipped with multiantenna transmitters and receivers is considered in the context of cognitive radio (CR...
— We consider a point-to-multipoint cognitive radio network that shares a set of channels with a primary network. Within the cognitive radio network, a base station (BS) controls...
Abstract— Spectrum management is used to improve performance in multiuser communication system, e.g., cognitive radio or femtocell networks, where multiuser interference can lead...
Abstract— Two driving goals for cognitive radio (CR) technique are maximizing spectrum utilization and avoiding interference to primary users. In this paper, we deal with the CR ...
