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-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 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 ... -
Experimental Characterization of Mobile Fading Channels Aiming the Design of Non-Wearable Fall Detection Radio Systems at 5.9 GHz
Firoozi, Farhad; Borhani, Alireza; Pätzold, Matthias Uwe (Chapter; Peer reviewed, 2016) -
Modelling and Analysis of Non-Stationary Mobile Fading Channels Using Brownian Random Trajectory Models
Borhani, Alireza (Doctoral dissertations at University of Agder;, Doctoral thesis; Peer reviewed, 2014)The demanding mobility features of communication technologies call for the need to advance channel models (among other needs), in which non-stationary aspects of the channel are carefully taken into consideration. Owing ... -
Modelling, Analysis, and Simulation of the Micro-Doppler Effect in Wideband Indoor Channels with Confirmation Through Pendulum Experiments
Abdelgawwad, Ahmed; Borhani, Alireza; Pätzold, Matthias Uwe (Journal article; Peer reviewed, 2020) -
On the spatial configuration of scatterers for given delay-angle distributions
Borhani, Alireza; Pätzold, Matthias (Journal article; Peer reviewed, 2014)This paper investigates the distribution of scatterers located around the mobile station (MS) for given delay-angle distributions. The delay-angle distribution function represents the joint probability density function ... -
On the spectral moments of non-WSSUS mobile-to-mobile double Rayleigh fading channels
Jaime-Rodriguez, J. J.; Gutierrez, Carlos Adrian; Pätzold, Matthias Uwe; Borhani, Alireza (IEEE International Symposium on Personal, Indoor, and Mobile Radio Communications workshops;2017, Journal article; Peer reviewed, 2018)This paper deals with the mathematical analysis of the spectral moments of non-wide-sensestationary uncorrelated-scattering (non-WSSUS) mobile-to-mobile (M2M) double-Rayleigh fading channels. The point of departure is a ... -
RF-Based Human Activity Recognition : A Non-stationary Channel Model Incorporating the Impact of Phase Distortions
Borhani, Alireza; Pätzold, Matthias Uwe (Chapter; Peer reviewed, 2019)This paper proposes a non-stationary channel model that captures the impact of the time-variant (TV) phase distortion caused by hardware imperfections. The model allows for studying the spectrogram of in-home radio channels ... -
The Impact of Human Walking on the Time-Frequency Distribution of In-Home Radio Channels
Borhani, Alireza; Pätzold, Matthias Uwe (Chapter; Peer reviewed, 2018) -
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 ...
