The research paper titled "NeRF2: Neural Radio-Frequency Radiance Fields" published by Dr Lei YANG’s team was awarded the Best Paper Award (Runner-up) at the 29th Annual International Conference on Mobile Computing and Networking (ACM MobiCom 2023). The co-authors of the paper are Dr Zhenlin AN, postdoctoral fellow and Ms Qingrui PAN and Mr Xiaopeng ZHAO, our PhD students.
The paper proposes a model called Neural Radio-Frequency Radiance Fields (NeRF^2), which is designed to predict the propagation of Radio Frequency (RF) signals in complex environments. The team trained the NeRF^2 model with a few signal measurements to predict the behaviour of a signal at any position when the location of a transmitter is known. The study demonstrated the effectiveness of NeRF^2 in applications such as indoor localisation and 5G MIMO technology. Read the paper: https://dl.acm.org/doi/10.1145/3570361.3592527
Additionally, the team also received a Graduate Award at ACM MobiCom 2023 for a demo developed by Dr YANG, Dr AN, Mr ZHAO and two COMP PhD students, Mr Jingyu TONG and Mr Sicong LIAO. This demo, namely “Radio Frequency Neural Networks for Wireless Sensing”, introduces an innovative architecture called RF Neural Network (RFNN) that emulates the functionalities of a conventional neural network in proximity to or within sensors. Leveraging reconfigurable metasurfaces, RFNN enables high-speed calculations on raw RF signals, offering processing capabilities at the speed of light. The initial findings highlight RFNN's potential in various wireless sensing applications, including material classification, localisation, and gesture recognition, while operating with minimal power consumption. This research holds promise for optimising the sensing capabilities of IoT devices.
