A 3D Non-Stationary Cluster Channel Model for Human Activity Recognition
Abdelgawwad, Ahmed; Pätzold, Matthias Uwe (Journal article; Peer reviewed, 2019)This paper proposes a three-dimensional (3D) non- stationary fixed-to-fixed indoor channel simulator model for human activity recognition. The channel model enables the formulation of temporal variations of the received ... -
A Framework for Activity Monitoring and Fall Detection Based on the Characteristics of Indoor Channels
Abdelgawwad, Ahmed; Pätzold, Matthias Uwe (Journal article; Peer reviewed, 2018)This paper concerns the Doppler power spectrum of three-dimensional non-stationary indoor fixed-to- fixed channels with moving people. In this paper, we model each moving person as a moving scatterer with time-variant (TV) ... -

Naderi, Meisam; Pätzold, Matthias Uwe; Hicheri, Rym; Youssef, Neji (Journal article; Peer reviewed, 2017) -
A Highly Flexible Trajectory Model Based on the Primitives of Brownian Fields---Part II: Analysis of the Statistical Properties
Borhani, Alireza; Pätzold, Matthias Uwe (Peer reviewed; Journal article, 2016) -
A Non-Isovelocity Geometry-Based Underwater Acoustic Channel Model
Naderi, Meisam; Zajic, Alenka G.; Pätzold, Matthias Uwe (Journal article; Peer reviewed, 2017) -
A Non-Stationary Channel Model for the Development of Non-Wearable Radio Fall Detection Systems
Borhani, Alireza; Pätzold, Matthias Uwe (Journal article; Peer reviewed, 2018)The emerging non-wearable fall detection systems rely on processing radio waves reflected off the body of the home user who has no active interaction with the system, increasing the user privacy and acceptability. This ... -
A Non-Stationary Mobile-to-Mobile Channel Model Allowing for Velocity and Trajectory Variations of the Mobile Stations
Dahech, Wiem; Pätzold, Matthias Uwe; Gutierrez, Carlos Adrian; Youssef, Neji (Journal article; Peer reviewed, 2017) -
A Non-Stationary Mobile-to-Mobile Channel Model Allowing for Velocity and Trajectory Variations of the Mobile Stations
Dahech, Wiem; Pätzold, Matthias Uwe; Gutierrez, Carlos Adrian; Youssef, Neji (Journal article; Peer reviewed, 2017)In mobile-to-mobile (M2M) communication systems, both the transmitter and the receiver are moving with a certain velocity, which is usually assumed to be constant over time. However, in realistic propagation scenarios, the ... -
A non-WSSUS mobile-to-mobile channel model assuming velocity variations of the mobile stations
Gutierrez, Carlos Adrian; Pätzold, Matthias Uwe; Dahech, Wiem; Youssef, Neji (Journal article; Peer reviewed, 2017)This paper aims to characterize the effects that the velocity variations of the mobile stations (MSs) produce on the correlation properties of non-stationary time-frequency (TF) dispersive mobile- to-mobile (M2M) fading ... -
A Novel Wideband MIMO Car-to-Car Channel Model Based on a Geometrical Semi-Circular Tunnel Scattering Model
Avazov, Nurilla; Pätzold, Matthias Uwe (Journal article; Peer reviewed, 2016) -
A Random Trajectory Approach for the Development of Nonstationary Channel Models Capturing Different Scales of Fading
Borhani, Alireza; Stüber, Gordon L.; Pätzold, Matthias Uwe (Journal article; Peer reviewed, 2017)This paper introduces a new approach to developing stochastic nonstationary channel models, the randomness of which originates from a random trajectory of the mobile station (MS) rather than from the scattering area. The ... -
Definition and Analysis of Quasi-Stationary Intervals of Mobile Radio Channels
Pätzold, Matthias Uwe; Gutierrez, Carlos Adrian (Chapter; Peer reviewed, 2018) -
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 ... -

Enhancing the Resolution of the Spectrogram of Non-Stationary Mobile Radio Channels by Using Massive MIMO Techniques
Pätzold, Matthias Uwe; Gutierrez, Carlos Adrian (Chapter; Peer reviewed, 2017)This paper is concerned with the enhancement of the resolution of the spectrogram of non-stationary mobile radio channels using massive multiple-input multiple-output (MIMO) techniques. By starting from a new generic ... -
