A Systematic Study: Channel Sounding via Modal Expansion

November 3, 2018
Author(s)
Alex Yuffa, Ben Jamroz, Jake Rezac, Dylan Williams
We present preliminary results of using a modal (partial wave) expansion of the field to characterize a propagation channel. We assume that the measurements of the scalar, two-dimensional field from which the modal expansion coefficients are obtained

Antenna Radiation Pattern Measurements in Reverberation Chamber

November 3, 2018
Author(s)
Audrey K. Puls
Antenna radiation pattern measurements are typically performed in anechoic chambers which are expensive to buy and inconvenient to rent from external facilities. This paper investigates the use of a reverberation chamber for antenna radiation pattern

3.5 GHz Federal Incumbent Protection Algorithms

October 21, 2018
Author(s)
Michael R. Souryal, Thao T. Nguyen, Nickolas J. LaSorte
The current standardized algorithm for U.S. federal incumbent protection in the 3.5 GHz band is sub-optimum in that it moves more commercial transmissions out of the protected channel than necessary, in most cases. This paper proposes a more efficient

PSCR 2017 Stakeholder Conference Presentation Materials -- Day 1

October 16, 2018
Author(s)
Jeremy E. Benson, Jeff Johnson, Eric W. Anderson, Carol Politi, TRX Systems, Inc., Anthony Rowe, A Shkel, Chenji Harsha, Nancy French, Murat Yuskel, Benjamin J. Posthuma, Margaret Pinson, Dereck R. Orr
This document is a compilation of the slides presented during Day 3 of the 2017 Public Safety Communications Research Program's (PSCR) Annual Stakeholder Conference. Day 3 topics include PSCR research plans and results for Location-Based Services

Correlation-Based Uncertainty in Loaded Reverberation Chambers

October 1, 2018
Author(s)
Maria G. Becker, Michael R. Frey, Sarah B. Streett, Catherine A. Remley, Robert D. Horansky, Damir Senic
When reverberation chambers are loaded to increase the coherence bandwidth for modulated-signal measurements, a secondary effect is decreased spatial uniformity. We show that an appropriate choice of stirring sequence, consisting of a combination of mode

Probability of Coexistence of LTE-LAA and WLAN Systems Based on Delay Constraints

July 29, 2018
Author(s)
Yao Ma, William Young, Eric W. Anderson, Jason Coder
To support efficient spectrum sharing and related standardization efforts in unlicensed spectrum, it is important to develop analytical tools to accurately quantify coexistence performance between long-term evolution license assisted access (LTE-LAA) and
