Morph: ChirpTransformer-based Encoder-decoder Co-design for Reliable LoRa Communication
Yidong Ren, Maolin Gan, Chenning Li +4
In this paper, we propose Morph, a LoRa encoder-decoder co-design to enhance communication reliability while improving its computation efficiency in extremely-low signal-to-noise r…
Security Defense For Smart Contracts: A Comprehensive Survey
Nikolay Ivanov, Chenning Li, Qiben Yan +3
The blockchain technology has been used for recording state transitions of smart contracts - decentralized applications that can be invoked through external transactions. Smart con…
WiVelo: Fine-grained Walking Velocity Estimation for Wi-Fi Passive Tracking
Chenning Li, Li Liu, Zhichao Cao +1
Passive human tracking via Wi-Fi has been researched broadly in the past decade. Besides straight-forward anchor point localization, velocity is another vital sign adopted by the e…
NEC: Speaker Selective Cancellation via Neural Enhanced Ultrasound Shadowing
Hanqing Guo, Chenning Li, Lingkun Li +3
In this paper, we propose NEC (Neural Enhanced Cancellation), a defense mechanism, which prevents unauthorized microphones from capturing a target speaker's voice. Compared with th…
