Untangling the Geometry and Speed for RF Sensing Spectrograms
Mert Torun, Darius Cuenca, Yasamin Mostofi
A fundamental challenge in RF sensing is that Doppler signatures observed by a link entangle the target's motion with the sensing geometry, resulting in limited applicability to un…
Opportunistic Data Offloading for Robotic Operations in Dynamically Varying Channel Environments
Heeirthan Shanthan, Winston Hurst, Yasamin Mostofi
This paper studies energy-efficient operation of autonomous vehicles (AVs) in dynamic environments with moving obstacles and while communicating over mmWave channels. The obstacles…
Untangling Dense Crowds with mmWave Radar: From Crowd Semantics to Individual Spatial Behaviors
Aaditya Prakash Kattekola, Anurag Pallaprolu, Yasamin Mostofi
In this paper, we present a novel framework for recovering individual footprints and pedestrian spatial behaviors in dense crowds. This is a highly challenging problem, as pedestri…
mmFlux: Crowd Flow Analytics with Commodity mmWave MIMO Radar
Anurag Pallaprolu, Winston Hurst, Yasamin Mostofi
