Abstract: Satellite communication is experiencing a revolution pushed by the unprecedented deployment of satellites in low-Earth orbit (LEO) constellations for connectivity solutions. Lower launch costs have encouraged private ventures to deploy broadband LEO networks targeting market opportunities like internet services for remote or under-served areas, mobile connectivity, governmental services, and communication services for emergency response and disaster relief. However, LEO satellite operators face several technical challenges which need to be addressed to unleash the full potential of this promising technology. We discuss broad trends that are changing the design of satellite communication networks fundamentally and the challenges to establish a LEO-based integration with current 5G and coming 6G cellular networks. Specifically, signal processing advances will be addressed with focus on multi-antenna transmit precoding techniques to improve coverage and spectral/energy efficiency, as well as link reliability and security. Recent activities related to standardization, experimental validations and demonstrations will also be presented. Bio: Björn Ottersten received the Ph.D. degree in electrical engineering from Stanford University, Stanford, CA, USA. He has held research positions at Linköping University, Stanford University, Katholieke Universiteit Leuven, and the University of Luxembourg. He has served as Director of Research with ArrayComm, Inc., a start-up in San Jose, CA, USA, based on his patented technology. He is Professor of signal processing with the Royal Institute of Technology (KTH), Stockholm, Sweden and the founding Director for the Interdisciplinary Centre for Security, Reliability and Trust, University of Luxembourg. He is a recipient of the IEEE Fourier Technical Field Award, the IEEE Signal Processing Society Technical Achievement Award, the EURASIP Group Technical Achievement Award, and the European Research Council (ERC) advanced research grant twice. He has authored journal papers that received the IEEE Signal Processing Society Best Paper Award in 1993, 2001, 2006, 2013, and 2019, and 9 IEEE conference papers best paper awards. He has been a board member of IEEE Signal Processing Society, EURASIP, the Swedish Research Council, the Swedish Foundation for Strategic Research and currently serves on the Scientific Council of the ERC. Dr. Ottersten has served on several editorial boards and is a fellow of IEEE, EURASIP, AAIA, the Royal Swedish Academy of Engineering Sciences.
