Towards Spatial Selection Transmission for Low-end IoT Devices with SpotSound

Published in ACM MobiCom 2023, 2023

We propose a neural-enhanced modulation scheme that leverages indoor multipath effects as a natural beamformer, enabling spatial selective transmission on low-end single-antenna IoT devices for the first time.

Neural-Enhanced Modulation for Spatial Selective Transmission on Low-End IoT Devices

Published in IEEE/ACM Transactions on Networking, 2026, 2026

We extend SpotSound with customizable spot sizes, synthetic CIR data generation for cross-scenario generalization, and relaxed channel reciprocity assumptions.

Enabling ‘See-and-Point’ Communication between Robots

Published in IEEE Transactions on Mobile Computing, 2026, 2026

We propose a physical-world addressing mechanism and vision-driven real-time scene-to-channel conversion, enabling robots to establish directional communication links using only an onboard camera.
