System Level Innovations

The System Level Innovations (SLI) Group focuses on different fields of signal processing such as Massive MIMO feedback and corresponding PHY-MAC transceiver design, non-orthogonal multiple access schemes, channel data processing and many more.

The group has long history of expertise in the fields on 3GPP link-, system-level simulations and channel modeling for 4G and 5G systems. As a result we maintain the Quadriga channel modeling framework and Chronos, which is Fraunhofer HHIs’ internal system-level simulation tool chain. Both are optimized to run our self-operated Scientific High-Performance Computing Cluster at Heinrich Hertz Institute.

Research Topics

Current research focuses on

  • LTE-Advanced Pro and 5G New Radio technologies
  • MIMO and Massive MIMO communication
  • Multiple-access schemes
  • Interference management

Current technology components are actively driven

  • Wireless channel modeling for 0.5-100 GHz and
  • Channel sounding and parameter extraction
  • Link- and system-level simulations according to 3GPP
  • High performance cluster computing for wireless system development
