Direction-Independent Human Activity Recognition Using a Distributed MIMO Radar System and Deep Learning
Waqar, Sahil; Muaaz, Muhammad; Pätzold, Matthias Uwe (Peer reviewed; Journal article, 2023)Modern monostatic radar-based human activity recognition (HAR) systems perform very well as long as the direction of human activities is either towards or away from the radar. The monostatic single-input single-output ... -
Human activity signatures captured under different directions using SISO and MIMO radar systems
Waqar, Sahil; Muaaz, Muhammad; Pätzold, Matthias Uwe (Peer reviewed; Journal article, 2022)In this paper, we highlight and resolve the shortcomings of single-input single-output (SISO) millimeter wave (mm-Wave) radar systems for human activity recognition (HAR). A 2 × 2 distributed multiple-input multiple-output ... -
Orientation-Independent Human Activity Recognition Using Complementary Radio Frequency Sensing
Muaaz, Muhammad; Waqar, Sahil; Pätzold, Matthias Uwe (Peer reviewed; Journal article, 2023)RF sensing offers an unobtrusive, user-friendly, and privacy-preserving method for detecting accidental falls and recognizing human activities. Contemporary RF-based HAR systems generally employ a single monostatic radar ... -
Time-Frequency Characteristics of In-Home Radio Channels Influenced by Activities of the Home Occupant
Borhani, Alireza; Pätzold, Matthias Uwe; Yang, Kun (Peer reviewed; Journal article, 2019)While aging is a serious global concern, in-home healthcare monitoring solutions are limited to context-aware systems and wearable sensors, which may easily be forgotten or ignored for privacy and comfort reasons. An ... -
A Trajectory-Driven 3D Non-Stationary mm-Wave MIMO Channel Model for a Single Moving Point Scatterer
Avazov, Nurilla; Hicheri, Rym; Muaaz, Muhammad; Sanfilippo, Filippo; Pätzold, Matthias Uwe (Peer reviewed; Journal article, 2021)This paper proposes a new non-stationary three-dimensional (3D) channel model for a physical millimeter wave (mm-Wave) multiple-input multiple-output (MIMO) channel. This MIMO channel model is driven by the trajectory of ... -
