On Convergence of the Upper Bound on the Ratio of Gain to Quality Factor

December 6, 2021
Author(s)
Alex Yuffa, Marc Valdez, Benoit Derat
An antenna's practical far-field distance can be estimated from the upper bound on the ratio of its gain to quality factor. This upper bound is an infinite series that can be truncated based on the desired far-field accuracy. We investigate the convergence

Deep Learning Based Link-Level Abstraction for mmWave Communications

November 18, 2021
Author(s)
Jian Wang, Neeraj Varshney, Jiayi Zhang, David W. Griffith, Nada T. Golmie
Link abstraction is an efficient way for predicting link-level performance (e.g., whether the receiver successfully receives packets through communication links). It can be used to support system-level simulation and facilitate link adaption. Nonetheless

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

Electro-optically derived millimeter-wave sources with phase and amplitude control

October 12, 2021
Author(s)
Bryan Bosworth, Nick Jungwirth, Kassi Smith, Jerome Cheron, Franklyn Quinlan, Ari Feldman, Dylan Williams, Nate Orloff, Chris Long
Integrated circuits are building blocks in millimeter-wave handsets and base stations, requiring nonlinear characterization to optimize performance and energy efficiency. Today's sources use digital-to-analog converters to synthesize arbitrary electrical

A Hybrid Wired/Wireless Deterministic Network for Smart Grid

July 26, 2021
Author(s)
Bin Hu, Hamid Gharavi
With the rapid growth of time-critical applications in smart grid, robotics, autonomous vehicles, and industrial automation, demand for high reliability, low latency and strictly bounded jitter is sharply increasing. High-precision time synchronization

Practical Resource Optimization of Quantum-Enabled Communication Channels

July 21, 2021
Author(s)
Jabir Marakkarakath Vadakkepurayil, FNU Nur Fajar Rizqi Annafianto, Ivan Burenkov, Abdella Battou, Sergey Polyakov
We introduce new practical modulation schemes inspired by the quantum measurement. We experimentally show that our quantum-enabled communication system optimizes the combined resource efficiency (CRE) beyond the classical, shot-noise-limited CRE.

Demonstration that Einstein-Podolsky-Rosen Steering Requires More than One Bit of Faster-than-Light Information Transmission

May 28, 2021
Author(s)
Yu Xiang, Michael Mazurek, Joshua Bienfang, Michael Wayne, Carlos Abellan, Waldimar Amaya, Morgan Mitchell, Richard Mirin, Sae Woo Nam, Qiongyi He, Marty Stevens, Krister Shalm, Howard Wiseman
Schrödinger held that a local quantum system has some objectively real quantum state and no other (hidden) properties. He therefore took the Einstein-Podolsky-Rosen (EPR) phenomenon, which he generalized and called 'steering', to require nonlocal

SoK: How (not) to Design and Implement Post-Quantum Cryptography

May 17, 2021
Author(s)
James Howe, Thomas Prest, Daniel Apon
Post-quantum cryptography has known a Cambrian Explosion in the last decade. What started as a very theoretical and mathematical area has now evolved into a sprawling research field, complete with side-channel resistant embedded implementations, large

In public safety communications, direct mode communication is essential to keep first responders connected, especially when there is no network coverage. Direct mode communication is supported in Third Generation Partnership Project (3GPP) Long Term

Vectorizing Green's Identities

May 5, 2021
Author(s)
Alex Yuffa
Green's theorem and Green's identities are well-known and their uses span almost every branch of science and mathematics. In this paper, we derive a vector analogue of Green's three scalar identities and consider some of their uses. We also offer a number
