In the demo at EUCNC 2024 | 6G Summit 2024, we showcase how the NVIDIA’s Neural receiver concept can be used to produce receiver structures that are specially optimized for a specific site deployment. On the one hand, we show that the neural receiver structure can be trained with standardized stochastic channel models, providing significant gains with respect to traditional MIMO receivers. However, the neural receiver can be fine-tuned with a limited amount of data obtained at the base-station’s deployment site, boosting its performance beyond that of the generically trained receiver.
This demo showcases a hardware-based validation setup for a neural-network based receiver for multi-user MIMO transmissions through a real 5G O-RAN network, which consist of the following elements :
