Configuration and Control of a Millimeter-Wave Synthetic Aperture Measurement System with Uncertainties

October 25, 2021
Author(s)
Alec J. Weiss, Jeanne Quimby, Rodney Leonhardt, Benjamin Jamroz, Dylan Williams, Kate Remley, Peter Vouras, Atef Elsherbeni
This paper discusses the configuration and control of a new millimeter wave over-the-air measurement system. This system provides unparalleled measurement accuracy, flexibility, and the ability to bound uncertainties on its measurements. The system also

NIST Security Awareness Study

October 25, 2021
Author(s)
Jody Jacobs, Julie Haney, Susanne M. Furman
This is a presentation for the September 28, 2021 FISSEA conference. This presentation is on the NIST Security Awareness Study. The goal of the study is to better understand the needs, challenges, practices, and professional competencies of federal

Verification of the Channel Estimator Evaluator

October 25, 2021
Author(s)
Jeanne Quimby, Alec Weiss, Atef Elsherbeni
Fifth-generation millimeter-wave communications rely on channel estimators to correctly predict the frequency response of the propagating channel. Millimeter-wave communication systems have non-ideal hardware performance, such as phase noise, which

Estimating Regions of Wireless Coexistence with Gaussian Process Surrogate Models

October 22, 2021
Author(s)
Jake Rezac, Noel C. Hess, Jason Coder
Simultaneous coexistence of multiple wireless communications systems sharing the same spectrum is critical for the success of modern and future communications. We develop a technique for estimating regions of wireless coexistence (RWC) – the transmission

Solvent-cast 3D Printing of Biodegradable Polymer Scaffolds

October 22, 2021
Author(s)
John Tolbert, Diana Hammerstone, Nathaniel Yuchimiuk, Jonathan Seppala, Lesley Chow
Three-dimensional (3D) printing is a popular technique to fabricate scaffolds for tissue engineering because of its ability to produce complex tissue-like architectures. Scaffolds are often 3D printed using biodegradable polymers like poly(caprolactone)

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
