Effective Radar Cross Section in Close-Range Joint Communication and Sensing Applications

July 14, 2025
Author(s)
Steve Blandino, Jelena Senic, Neeraj Varshney, Jihoon Bang, Jack Chuang, Samuel Berweger, Jian Wang, Camillo Gentile, Nada Golmie
Radar Cross Section (RCS) is traditionally mea- sured under far-field conditions where targets are fully illumi- nated by the antenna beam. However, in close-range scenarios, such as those encountered in Joint Communication and Sensing (JCAS) systems, the

Quasi-Deterministic Channel Propagation Model for Human Sensing: Gesture Recognition Use Case

July 9, 2025
Author(s)
Jack Chuang, Raied Caromi, Jelena Senic, Samuel Berweger, Neeraj Varshney, Jian Wang, Anuraag Bodi, Camillo Gentile, Nada Golmie
We describe a quasi-determinstic channel propagation model for human gesture recognition reduced from real-time measurements with our context aware channel sounder, considering four human subjects and 20 distinct body motions, for a total of 120,000

Digital-Twin-Assisted Clustering of Radio-Frequency Multipath Components

Author(s)
Anuraag Bodi, Jihoon Bang, Neeraj Varshney, Samuel Berweger, Chiehping Lai, Jelena Senic, Jack Chuang, Camillo Gentile
Clustering radio-frequency (RF) multipath components (MPCs) fosters compact channel models by capturing the geometry of the scattering environment, yet "blind" methods based solely on RF data struggle to associate MPCs with individual scatterers. We

Measuring the RCS of Multipoint-Scattering Targets in JCAS Channel Sounding

Author(s)
Camillo Gentile, Jack Chuang, Steve Blandino, Jelena Senic, Jihoon Bang, Samuel Berweger
This paper presents a methodology for measuring the radar cross-section (RCS) of a target that scatters power from multiple points on its surface, in the context of joint communication and sensing (JCAS). By leveraging the fine resolution of millimeter

Using Temporal Consistency for Compressed Sensing in High-Resolution mmWave Sounding

March 18, 2025
Author(s)
Rudolph Semper, Jack Chuang, Samuel Berweger, Camillo Gentile
Switched phased array systems operating at high sample rates generate large amounts of data during measurements of radio channels, but many scenarios contain only few multipath components. Compressed Sensing suggests in these cases Nyquist-rate samples are

Algorithm-Supervised Millimeter Wave Indoor Localization using Tiny Neural Networks

January 17, 2025
Author(s)
Anish Shastri, Steve Blandino, Camillo Gentile, Chiehping Lai, Paolo Casari
The quasi-optical propagation of mmw signals has been instrumental in designing high-accuracy localization algorithms. These algorithms either exploit the geometric properties of the mmw signals or are based on an environment's radio footprints, leading to

Measurement-Based Prediction of mmWave Channel Parameters Using Deep Learning and Point Cloud

August 2, 2024
Author(s)
Anuraag Bodi, Raied Caromi, Jian Wang, Jelena Senic, Camillo Gentile, Hang Mi, Bo Ai, Ruisi He
Millimeter-wave (MmWave) channel characteristics are quite different from sub-6 GHz frequency bands. The major differences include higher path loss and sparser multipath components (MPCs), resulting in more significant time-varying characteristics in

AI-Based Environment Segmentation Using a Context-Aware Channel Sounder

April 26, 2024
Author(s)
Anuraag Bodi, Samuel Berweger, Raied Caromi, Jihoon Bang, Jelena Senic, Camillo Gentile
We describe how the data acquired from the camera and Lidar systems of our context-aware radio-frequency (RF) channel sounder is used to reconstruct a 3D mesh of the surrounding environment, segmented and classified into discrete objects. First, the images

Context-Aware Channel Sounder for AI-Assisted Radio-Frequency Channel Modeling

April 26, 2024
Author(s)
Camillo Gentile, Jelena Senic, Anuraag Bodi, Samuel Berweger, Raied Caromi, Nada Golmie
We describe a context-aware channel sounder that consists of three separate systems: a radio-frequency system to extract multipaths scattered from the surrounding environment in the 3D geometrical domain, a Lidar system to generate a point cloud of the

Author(s)
Jian Wang, Jack Chuang, Samuel Berweger, Camillo Gentile, Nada T. Golmie
Sensing with communication waveforms has drawn growing interest thanks to the ubiquitous availability of wireless networks. However, the required sensing resources may not always be available in a communication system. In addition, the communication system

Adaptive Channel-State-Information Feedback in Integrated Sensing and Communication Systems

Author(s)
Neeraj Varshney, Samuel Berweger, Jack Chuang, Steve Blandino, Jian Wang, Neha Pazare, Camillo Gentile, Nada T. Golmie
Efficient design of integrated sensing and communication systems can minimize signaling overhead by reducing the size and/or rate of feedback in reporting channel state information (CSI). To minimize the signaling overhead when performing sensing

Cluster Association for 3D Environment Based on 60 GHz Indoor Channel Measurements

May 31, 2023

Raied Caromi, Jian Wang, Anuraag Bodi, Camillo Gentile
In this paper, we present a ray tracing (RT) assisted multipath cluster association method. This work is based on an indoor channel measurement at 60 GHz, where a light detection and ranging (LiDAR) sensor was co-located with channel sounder and time

March 26, 2023
Author(s)
Jack Chuang, Camillo Gentile
In recent work, we proposed sweeping the antennas of phased arrays and beamforming in postprocessing – what we coined switched beamforming – instead of sweeping beams through analog beamforming – what the arrays are designed for. Not only is it orders of

Scalable Modeling of Human Blockage at Millimeter-Wave: A Comprehensive Analysis of Knife-Edge Diffraction, the Uniform Theory of Diffraction, and Physical Optics Against 60 GHz Channel Measurements

December 22, 2022

Human blockage at millimeter-wave frequencies is most commonly modeled through Knife-Edge Diffraction (KED) from the edges of a vertical strip. Although extensively validated through controlled laboratory experiments, the method does not scale to realistic
