Group “Satellite Communications Techniques”



The research group „Satellite Communications Techniques“ is concerned with new transmission techniques and new concepts for future satellite communications systems. Main targets are the improvement of bandwidth and power efficiency, the  improvement of transmission quality, higher throughput and data rates, and the development of new application areas. All kinds of satellite systems are taken into account, mobile and broadband systems, systems for commercial or governmental use, or systems for space exploration.

Research areas of the group are:

Channel Measurements and Channel Modeling for Mobile and Broadband SatComs

  • L, S, Ku, Ka, and Higher Frequency Bands

Fade Mitigation Techniques for Satellite Systems

  • Adaptive Coding and Modulation
  • Diversity Methods

Interference Management

  • Pre-Coding
  • Interference Cancellation
  • Resource Management to reduce Interference

On-Board Switching

Air Interface and Receiver Design

Protocol Design and Verification

  • MAC layer
  • Network Coding

Very High Throughput Satellite Systems

GEO Data Relais

SDR and FPGA Testbeds

The group is conducting system- and protocol simulations for performance analysis as well as demonstrations and measurements. Experimental satellite terminals are available for the demonstration of new algorithms and transmission techniques.
