Τίτλος: “Recent Advances in Modulation Techniques for Dynamic Spectrum Access”
Περίληψη: In this presentation, we will talk about issues related to Dynamic and Opportunistic Spectrum Access (DOSA) in Heterogenous Wireless Networks and particularly about modulation techniques that are considered suitable for the implementation of the DOSA concept. Over the last 10 years or so, Filter Bank Multicarrier modulation (FBMC) schemes have emerged as a promising solution for DOSA because they are assumed to protect the Primary User’s (PU) signal due to their inherent good Power Spectrum Density properties. However, it has been shown recently that if we look at the Quality of Service (QoS) of the PU, the above statement may not be true. This has been shown by analyzing the degradation at the PU side, just after demodulation. The theoretical results have been confirmed by simulations and also by true testbed experiments. The performance degradation of the PU signal when a Secondary User (SU) appears in the network, indicates that FBMC may not offer the required performance guarantees in the context of DOSA.
Σύντομο βιογραφικό ομιλητή: Prof. Jacques PALICOT received, in 1983, his PhD degree in Signal Processing from the University of Rennes. Since 1988, he has been involved in studies about equalization techniques applied to digital transmissions and analog TV systems. Since 1991 he has been involved mainly in studies concerning the digital communications area and automatic measurements techniques. He has taken an active part in various international bodies EBU, CCIR, URSI, and within RACE, ACTS and IST European projects. He has published various scientific articles notably on equalization techniques, echo cancellation, hierarchical modulations and Software Radio techniques. He is author or co-author of more than 300 publications with more than 50 in journals, two books and 22 patents.
He is currently involved in adaptive Signal Processing, digital communications, Software Radio, Cognitive radio and Green Radio. From November 2001 to September 2003 he had a temporary position with INRIA/IRISA in Rennes.
He serves as Associate Editor for EURASIP JASP since 2008. He also served as lead guest editor for several Special Issues on Software Radio, Cognitive Radio and Green Radio. He was Co General Chairman of ISCIT 2011, Co General Chairman of Next-GWiN 2014, Technical Program Chairman of CROWNCOM 2009, Technical Program Chairman of GREENCOM 2013 and Technical Program Chairman of CRN Symposium of ICC 2014.
Since October 2003 he is with CentraleSupélec in Rennes where he leads the Signal Communications and Embedded Electronics (SCEE) research team.
