Faouzi Bader received his PhD degree (with Honours) in Telecommunications in 2002 from Universidad Politécnica de Madrid (UPM), Madrid-Spain. He joined the Centre Technologic de Telecomunicacions de Catalunya (CTTC) in Barcelona-Spain as research associate in 2002, and From 2006-2013 as Senior Research Associate. Since June 2013, he is as associate professor at École Supérieur D'Electricité- SUPELEC in France.
His research activities mainly focus on IMT-Advanced systems, cross layer system design, multicarrier waveforms (OFDM(A), (non-) uniform multimode filter based multicarrier schemes) and frequency allocation in relay cognitive environment. He has been involved in several European projects from the 5th-7th EC research frameworks, and from 2012-2013 the general coordinator and manager of the EC funded  ICT "EMPhAtiC" project focusing on "Enhanced Multicarrier Techniques for Professional Ad-Hoc and Cell-Based Communications". He has published over 110 papers in peer-reviewed journals and international conferences, more than 13 book chapters, and 3 books. He served as Technical Program Committee member in major IEEE ComSoc and VTS conferences (ICC, PIMRC, VTC spring/fall, WCNC, ISWCS, GLOBECOM, ICT), and also as Session Chair member (WCNC, PIMRC, VTC-Spring/Fall) over last years, the general chair of the eleventh edition of the ISWCS'2014 conference, and the co-chair of the ISWCS 2015 edition. He is IEEE Senior Member since 2007. More info at:



It is too early to exactly define what the 5G wireless communication networks will be at this moment. However, the 5G radio access  must cope with very different requirements and to be able to interact and coexist with different devices (standards) in an heterogeneous communication environment, and support communications in some special scenarios not envisaged by 4G networks. There is no doubt that multicarrier (MC) scheme will still be considered as the most appropriate scheme for spectrum coexistence and secondary access in future 5G systems due its flexibility in allocating different resources among different users as well as its ability to fill the spectrum holes left by the primary users. A look on the effect of the communication waveform choice on the system performance ( i.e. capacity and  guard band) will be addressed considering the coexistence with narrow band communications and in scenarios with synchronisation relaxation/loss.
