The ever increasing number of communicating devices, along with high speed applications are challenging existing wireless networks and driving the transition to the next generation of mobile networks. Future communications target highly ambitious objectives, among which, a large increase in network capacity and throughput, an explosion of the number of users... In order to reach these goals, various candidate technologies are envisioned, such as cognitive radio and cooperative communications. This talk focuses on the design of an optimal power allocation policy for a relay-aided cognitive network composed by a primary and secondary user/destination pair and a full-duplex relay that helps the communication between the secondary user and destination. Both the secondary user and the relay are allowed to transmit provided that a minimum quality of service (QoS) constraint is met. The aim is to maximize the achievable rate for the secondary user under three constraints: the primary QoS, and two individual power constraints for both the secondary user and the relay. Throughout the talk, we focus on two relaying schemes proposed for cooperative communications, namely Decode-and-Forward and Compress-and-Forward.


Anne Savard received the Eng. degree in Electrical Engineering with specialization in Multimedia Systems from the Ecole Nationale Supérieure de l'Electronique et de ses Applications (ENSEA), Cergy-Pontoise, France, and the M.Sc. degree in Intelligent and Communicating Systems from Université Cergy-Pontoise, both in 2012. From October 2012 to September 2015, she was a PhD student at ETIS Laboratory/ENSEA, under the supervision of Claudio Weidmann and David Declercq. From October 2015 to August 2016, she was a postdoctoral researcher working with Matthieu Bloch on physical layer security and covert communications. Since September 2016, she is an associate professor (enseignant chercheur) at IMT Lille Douai (ex Telecom Lille). Her research interests include channel coding, resource allocation, cooperative communication and multi-user information theory.
