This webinar describes technical challenges of 5G non-terrestrial communications networks (NTNs) implemented with low earth orbiting (LEO) satellites. It then describes how you can address those challenges through modeling and simulating the satellites and their orbits, the physical layer communications links, the power amplifiers used on those links, and the Doppler processing required to counteract the satellite motion. You will also learn how you can generate a SatCom channel model with time-varying delay, Doppler, and path loss, and implement that channel model with a Rohde & Schwarz hardware channel emulator, for testing purposes.
Highlights
- Modeling large satellite constellations
- Analyzing and visualizing time-varying visibility and comms link closure
- Modeling PAs and Doppler compensation
- Generating a “hardware-friendly” channel model
- Implementing that channel model on hardware
About the Presenters
Reiner Stuhlfauth is a technology manager wireless from the Test & Measurement Division of Rohde & Schwarz in Munich. Before that he worked as a trainer and has more than 20 years of experience in teaching and promoting mobile communication technologies in the background of cellular standards and non-cellular technologies. He is involved in several projects concerning 5G, 5G advanced and 6G research activities. Reiner is one of the authors of the R&S technology book “5G New Radio – fundamentals, procedures, testing aspects”. He holds the academic degree of engineer in telecommunications (Dipl.-Ing) issued by the Technical University of Kaiserslautern.
Mike McLernon is an advocate for communications and software-defined radio products at MathWorks. Since joining MathWorks in 2001, he has overseen the development of numerous PHY layer capabilities in Communications Toolbox, and of connectivity to multiple SDR hardware platforms. He has worked in the communications field for over 35 years, in both the satellite and wireless industries. Mike received his BSEE from the University of Virginia and his MEEE from Rensselaer Polytechnic Institute. He is a senior member of the IEEE.
Jean-Pierre Messmer is a product manager in the signal generator department of Rohde & Schwarz where he is responsible for satellite communication applications. He has a master's degree in electrical engineering from the Karlsruhe Institute of Technology with a specialization in communications engineering as well as an MBA from the Collège des Ingénieur.
