Robust Two-Way Cognitive Relaying: Precoder Designs under Interference Constraints and Imperfect CSI

We present various robust precoder designs for two-way relaying in a cognitive radio network, where a pair of cognitive (or secondary) transceiver nodes communicate with each other assisted by a set of cognitive two-way relays. The secondary nodes share the spectrum with a licensed primary user (PU)...
