Abstract

Flexibility in radio resource management and in the scheduling of users is of outmost importance in the evolution of wireless communication systems. In this respect, and among other paradigms, future smart networks leverage the potential of ubiquitous cell-free communications to overcome the inter-cell interference limitation in cellular networks and provide additional macro-diversity. We refer to this paradigm as large scale wireless networks and they can be implemented either in the terrestrial or in the satellite communication segment. This talk presents the cell-free or beam-free concept in the satellite segment, which is a large scale network that is less known than the terrestrial one. Then the potential of taking into account the geometric structure of the user requirements is shown with the application of graph clustering techniques. The talk also highlights the challenges of dealing with heterogeneous types of content and discusses open problems for signal processing on graphs. 

Speaker bio

Ana Pérez-Neira is a full professor at UPC (Technical University of Catalonia) in the Signal Theory and Communication Department. Her research topic is signal processing for communications and currently she is working in multi-antenna and multi-carrier signal processing, both for satellite communications and wireless systems. She was on the board of directors of ETSETB (Telecom Barcelona) from 2000-03 and Vicerector for Research at UPC (2010-13). She created the UPC Doctoral School (2011). Currently, she is the Scientific Coordinator at CTTC (Centre Tecnològic de Telecomunicacions de Catalunya), where she is a fellow researcher. From 2008-2016 she has been a member of EURASIP BoD (European Signal Processing Association), from 2010-2016 she was a member of IEEE SPTM (Signal Processing Theory and Methods), since 2017 she's been IEEE SPS Regional Director-at-Large by election, and she has been elected as IEEE SPS member of the BoG from 2019-2020. She is the coordinator of the European project SANSA and of the Network of Excellence on satellite communications, financed by the European Space Agency: SatnexIV. She has been the leader of 20 projects and has participated in over 50 (10 for the European Space Agency). She is author of 50 journal papers (20 related with Satcom) and more than 200 conference papers (20 invited). She is co-author of 4 books and 5 patents (one on satcom). She has been guest editor in 5 special issues and associate editor of the IEEE Transactions on Signal Processing and EURASIP Signal Processing and Advances in Signal Processing. Currently she is a member of the IEEE SPCOM (Signal Processing for Communications) technical committee. She has been the general chairman of IWCLD’09, EUSIPC’11, EW’14, IWSCS’14 and ASMS/SPSC’16. She is a recipient of the 2018 EURASIP Society Award. She is the general chair of IEEE ICASSP’20.
