Cooperative Filter-and-Forward Beamforming in Cognitive Radio Relay Networks

Cooperative Filter-and-Forward Beamforming in Cognitive Radio Relay Networks

In this paper, the Filter-and-Forward strategy is developed for cooperative relays in Cognitive Radio networks with underlay structure and frequency selective fading channels. A cost function is defined to minimize the required transmitting power of the relay networks and the secondary user. This is...
