Towards an AI-native air interface for 6G: Rohde & Schwarz and NVIDIA showcase AI/ML-based neural receiver with custom modulation at Brooklyn 6G Summit
At this year’s Brooklyn 6G Summit, taking place from October 31 to November 2 in Brooklyn, New York, visitors can experience the first demonstration of how a neural receiver paired with a learned custom modulation performs in a 5G NR uplink multiple input multiple output (UL MIMO) scenario. The setup combines premium test solutions for signal generation and analysis from Rohde & Schwarz and the NVIDIA Sionna™ GPU-accelerated open-source library for 5G and 6G link-level simulations. NVIDIA’s Sionna enables rapid prototyping of complex communications system architectures and provides native support to the integration of machine learning in 6G signal processing.
This demonstration builds on the successful showcase at the Mobile World Congress 2023 in Barcelona, where both companies demonstrated the concept of a neural receiver in a hardware-in-the-loop experiment involving two independent companies for the very first time. Academia, leading research institutes, and key industry experts across the globe anticipate that a future 6G standard will use AI/ML for signal processing tasks, such as channel estimation, channel equalization, and demapping. This concept is understood as a neural receiver. Today’s simulations suggest that a neural receiver will improve overall link performance and thus throughput compared to the current high-performance deterministic software algorithms used in 5G NR while keeping computational complexity at a manageable level..
