RaStream: Edge-Deployable Streaming Human Mesh Recovery from mmWave Radar

Millimeter-wave (mmWave) radar provides a privacy-preserving sensing modality for human motion analysis, yet continuous SMPL-X recovery on edge devices remains challenging because accurate reconstruction benefits from dense volumetric radar observations that preserve weak articulated reflections, while repeatedly proce...

A Universal Random Precoding Framework for MIMO Systems

Current wireless systems combat inter-symbol interference (ISI) by diagonalizing or sparsifying the channel matrix, yet they remain vulnerable to selective fading. To address this, we propose a universal random precoding (RP) transmission framework based on the universality class. RP leverages random transforms to stat...
