Wideband Synthetic-Aperture Millimeter-Wave Spatial-Channel Reference System With Traceable Uncertainty Framework

January 24, 2023
Author(s)
Kate Remley, Peter Vouras, Ben Jamroz, Alec Weiss, Jeanne Quimby, Dylan Williams, Rod Leonhardt, Damla Guven, Rob Jones, Joshua Kast
This paper describes a wideband synthetic-aperture system and the associated Fourier processing for generating high-resolution spatial and temporal estimates of the signal propagation environment in wireless communication channels at millimeter-wave

Telecommunication Testbed Repeatability Assessment

September 16, 2022
Author(s)
Jeanne Quimby, Jake Rezac, Mary Gregg, Michael Frey, Jason Coder, Anna Otterstetter
Telecommunication testbeds are a fundamental tool in communication research, enabling prototyping and validating new ideas. Unfortunately, these testbeds are often highly complex, costly, and challenging to operate, requiring simultaneous Open System

Welcome to SAMURAI's software!

August 29, 2022
Author(s)
Alec Weiss, Jeanne Quimby, Rod Leonhardt
This project is anticipated to generate a software package for automation of the SAMURAI platform, Working Data, Derived Data, and Published Results. Working Data will comprise raw measurement information from vector network analyzer or camera array

Finding Kinship in the Women in Radio Science (WIRS) Chapter

August 17, 2022
Author(s)
Reyhan Baktur, zoya popovic, Jeanne Quimby, Emily Porter
This paper introduces the Women in Radio Science, the newest Chapter of the US National Committee of the International Union of Radio Science. The unique challenges of minority groups in radio science community are discussed. Value and impact of

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

Monte Carlo Augmented Channel Estimator

March 3, 2022
Author(s)
Alec Weiss, Atef Elsherbeni, Jeanne Quimby, Jake Rezac
We have developed a novel Monte Carlo-augmented channel estimator for millimeter-wave orthogonal frequency division multiplexing systems To better estimate and correct a transmitted orthogonal frequency division multiplexed signal by incorporating the

Welcome to SAMURAI's documentation!

January 13, 2022
Author(s)
Alec Weiss, Jeanne Quimby, Rod Leonhardt, Ben Jamroz, Peter Vouras, Kate Remley, Dylan Williams
The National Institute of Standards and Technology (NIST) Communication Technology Laboratory (CTL) developed the Synthetic Aperture Measurement with Uncertainties and Angle of Arrival (SAMURAI) millimeter-wave testbed and technique. SAMURAI utilizes a

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

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

Timing Offset and Timing Stability for Dual-Clock Systems

May 4, 2021
Author(s)
Joshua Kast, Jeanne Quimby, Jake Rezac, Stefania Romisch
In this work, we describe a mathematical framework for evaluating timing offset and timing noise in channel sounders, based on a second-order deterministic model, and a stochastic metric based on the Allan Deviation. Using this framework, we analyze the

Frequency Invariant Beampatterns for Wideband Synthetic Aperture Channel Sounders

May 29, 2020
Author(s)
Peter G. Vouras, Jeanne T. Quimby, Benjamin F. Jamroz, Alec J. Weiss, Rodney W. Leonhardt, Dylan F. Williams, Catherine A. Remley
This paper derives two novel frequency invariant beamformers (FIBs) for use with wideband synthetic aperture channel sounders. Results using measured data show that the choice of beam pattern can affect the amount of diffuse multipath energy received
