Comparative Analysis and Behavioral Modelling of Power Amplifiers in FR3
Cel Thys, Rodney Martinez Alonso, Ali H Alsarraf +3
Power amplifier (PA) nonlinearity is a critical transmitter impairment in the upper mid-band (7 GHz to 24 GHz), designated as Frequency Range 3 (FR3) in emerging 6G standardisation…
RT-VSS: In-House Ray Tracing for Vital Signs Sensing in FR3 Band
Rudranil Chattopadhyay, Zhuangzhuang Cui, Achiel Colpaert +1
Vital Signs Sensing, enabled by the evolution of wireless communications, is inherently challenging as the chest's micro-Doppler signatures can be corrupted by multipath, body move…
Near-Field Velocity Estimation and Doppler-Aware Localization in OFDM Massive MIMO
Qing Zhang, Dario Tagliaferri, Robbert Beerten +3
In Orthogonal Frequency Division Multiplexing (OFDM)-based massive Multiple-Input Multiple-Output (MIMO) near-field (NF) sensing, target motion induces an antenna-dependent bistati…
Dualband OFDM Delay Estimation for Multi-Target Localization
Jialun Kou, Achiel Colpaert, Zhuangzhuang Cui +1
Integrated localization and communication systems aim to reuse communication waveforms for simultaneous data transmission and localization, but delay resolution is fundamentally li…
Robust Localization in OFDM-Based Massive MIMO through Phase Offset Calibration
Qing Zhang, Adham Sakhnini, Robbert Beerten +4
Accurate localization in Orthogonal Frequency Division Multiplexing (OFDM)-based massive Multiple-Input Multiple-Output (MIMO) systems depends critically on phase coherence across…
Near-Field Spatial non-Stationary Channel Estimation: Visibility-Region-HMM-Aided Polar-Domain Simultaneous OMP
Thibaut Ceulemans, Cel Thys, Robbert Beerten +2
This work focuses on channel estimation in extremely large aperture array (ELAA) systems, where near-field propagation and spatial non-stationarity introduce complexities that hind…
BS-Breath: Respiration Sensing with Cell-free Massive MIMO
Haoqiu Xiong, Robbert Beerten, Zhuangzhuang Cui +2
This paper demonstrates the feasibility of respiration pattern estimation utilizing a communication-centric cellfree massive MIMO OFDM Base Station (BS). The sensing target is typi…
