Towards Opportunistic Radar Sensing Using Millimeter-wave WiFi

January 1, 2024
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

August 28, 2023
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

On Predistortion Filtering for Switched Beamforming With Phased-Array Antennas

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
Author(s)
Anmol Bhardwaj, Camillo Gentile, Jelena Senic
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

Integrated Sensing and Communication: Enabling Techniques, Applications, Tools and Datasets, Standardization, and Future Directions

December 1, 2022
Author(s)
Jian Wang, Neeraj Varshney, Camillo Gentile, Steve Blandino, Jack Chuang, Nada T. Golmie
The design of integrated sensing and communication (ISAC) systems has drawn recent attention for its capacity to solve a number of challenges. Indeed, ISAC can enable numerous benefits, such as the sharing of spectrum resources, hardware, and software, and

Multi-User MIMO Enabled Virtual Reality in IEEE 802.11ay WLAN

May 16, 2022
Author(s)
Jiayi Zhang, Steve Blandino, Neeraj Varshney, Jian Wang, Camillo Gentile, Nada T. Golmie
Virtual reality (VR) coupled with 360° video has been used in a variety of areas, including gaming, remote learning, and healthcare, among others. The 360° video on which VR applications are based today is mostly low resolution and, in order to improve the

Methodology for Measuring the Frequency Dependence of Multipath Channels Across the Millimeter-Wave Bands

April 19, 2022
Author(s)
Damla Guven, Ben Jamroz, Jack Chuang, Camillo Gentile, Rob Horansky, Kate Remley, Dylan Williams, Jeanne Quimby, Rod Leonhardt
Millimeter-wave (mmWave) communications promise Gigabits-per-second data rates thanks to the availability of large swaths of bandwidth between 10–100 GHz. Although cellular operators prefer the lower portions of the bands due to the general belief that

Markov Multi-Beamtracking in SU-MIMO with 60 GHz Mobile Channel Measurements

December 28, 2021
Author(s)
Steve Blandino, Jelena Senic, Camillo Gentile, Derek Caudill
Beamforming training refers to the exhaustive scan over which the receiver and transmitter beams are steered along a predefined set of angles to determine the beam pairs that coincide with the dominant channel paths, for spatial multiplexing. In the

Anaylsing the 3GPP Spatial Consistency Procedure through Channel Measurements

October 21, 2021
Author(s)
Camillo Gentile, Chiehping Lai
Millimeter-wave channel measurements for a meeting room, lecture room and open plan office floor were used to analyse and model the spatial consistency of channel clusters. Particularly, how the angle of arrivals and delays of extracted multi-path

Quasi-Deterministic Channel Propagation Model for an Urban Environment at 28 GHz

April 16, 2021
Author(s)
Neeraj Varshney, Jian Wang, Chiehping Lai, Camillo Gentile
We reduced parameters of the Quasi-Deterministic channel propagation model, recently adopted by the IEEE 802.11ay task group for next-generation Wi-Fi at millimeter-wave, from measurements collected in an urban environment with our 28 GHz directional

Geometrical-Empirical Channel Propagation Model for Human Presence at 60 GHz

March 2, 2021
Author(s)
Camillo Gentile, Anmol Bhardwaj, Derek Caudill, Peter B. Papazian, Jack Chuang, David Michelson
Previous efforts to develop simulation and/or measurement-based channel propagation models for the effect of human blockage on millimeter-wave communication systems have yielded important results, but lack either accuracy, generality, or simplicity. To

Over-The-Air Calibration of a Dual-Beam Dual-Polarized 28-GHz Phased-Array Channel Sounder

July 9, 2020
Author(s)
Sung Yun Jun, Derek Caudill, Jelena Senic, Camillo Gentile, Jack Chuang, Nada T. Golmie
This paper describes an over-the-air calibration procedure for the impulse response of a 28-GHz phased-array antenna channel sounder. The silicon-germanium (SiGe) antenna board is composed from two 8x8 planar arrays; each array can generate a distinct beam

Penetration Loss at 60 GHz for Indoor-to-Indoor and Outdoor-to-Indoor Mobile Scenarios

July 8, 2020

June 11, 2020
Author(s)
Jack Chuang, Jelena Senic, Chunmei Liu, Camillo Gentile, Sung Yun Jun, Derek Caudill
Millimeter-wave channel sounders are much more sensitive to phase drift than their microwave counterparts by virtue of shorter wavelength. This matters when coherently phasing (electronic or mechanical) antenna scans collected over seconds, minutes, or
