3D Point Splatting for mmWave Radar Novel View Synthesis
Adnan Armouti, Yixuan Gao, Rajalakshmi Nandakumar
Solving novel view synthesis (NVS) for millimeter-wave (mmWave) radar requires a renderer that is physically faithful, complex-valued, and multi-viewpoint-tractable. No prior metho…
mmIR: Frequency-Space Inverse Rendering for 3D Millimeter-Wave Radar ADC Synthesis
Adnan Armouti, Yixuan Gao, Rajalakshmi Nandakumar
High-resolution 3D radar data is scarce. Commodity mmWave sensors use small antenna arrays that limit angular resolution to several degrees, and existing datasets provide only 2D r…
mmFHE: mmWave Sensing with End-to-End Fully Homomorphic Encryption
Tanvir Ahmed, Yixuan Gao, Adnan Armouti +1
We present mmFHE, the first system that executes the entire cloud-side mmWave sensing pipeline including the DSP and ML inference under fully homomorphic encryption (FHE). mmFHE en…
SoilSound: Smartphone-based Soil Moisture Estimation
Yixuan Gao, Tanvir Ahmed, Shuang He +2
Soil moisture monitoring is essential for agriculture and environmental management, yet existing methods require either invasive probes disturbing the soil or specialized equipment…
WixUp: A General Data Augmentation Framework for Wireless Perception in Tracking of Humans
Yin Li, Rajalakshmi Nandakumar
Recent advancements in wireless perception technologies, including mmWave, WiFi, and acoustics, have expanded their application in human motion tracking and health monitoring. They…
CoPlay: Audio-agnostic Cognitive Scaling for Acoustic Sensing
Yin Li, Bo Liu, Rajalakshmi Nanadakumar
