Hierarchical prior zero-forcing for cognitive relaying
Electronics & Communications Engineering Department
In this paper, cognitive radio relaying in the physical layer is investigated where the cognitive base station (CBS) relays the PU's signal while transmitting its own signals to its secondary users (SUs). A new and simple linear method for beamforming, based on zero-forcing beamforming, adapted for the different levels of priority that users may possess in a cognitive radio network, is proposed and the special case of two SUs is analytically studied. © 2014 IEEE.
