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.
