SNR/CRB-Constrained Joint Beamforming and Reflection Designs for RIS-ISAC Systems
IEEE Transactions on Wireless Communications, 2023In this paper, we investigate the integration of integrated sensing and communication (ISAC) and reconfigurable intelligent surfaces (RIS) for providing wide-coverage and ultra-reliable communication and high-accuracy sensing functions. In particular, we

NELoRa: Towards Ultra-low SNR LoRa Communication with Neural-enhanced Demodulation
ACM International Conference on Embedded Networked Sensor Systems, 2021Low-Power Wide-Area Networks (LPWANs) are an emerging Internet-of-Things (IoT) paradigm marked by low-power and long-distance communication. Among them, LoRa is widely deployed for its unique characteristics and open-source technology.
