Noncoherent mmWave Path Tracking

Proceedings of the 18th International Workshop on Mobile Computing Systems and Applications, 2017
Millimeter (mm) wave picocellular networks have the potential for providing the 1000X capacity increase required to keep up with the explosive growth of mobile data. However, maintaining beams towards mobile users and adapting to frequent blockage, requires efficient, dynamic path tracking algorithms.

User Association in 5G mmWave Networks

2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017
The approaching 5G era of cellular communications is posing stringent performance requirements. New groundbreaking applications can be enabled only by means of multi-Gbps data rates and ultra-low latencies. The spectrum scarcity at frequencies below 6 GHz stimulated a new wave of wireless research that focuses on higher bands, namely mmWave ...

Unsupervised mmWave Beamforming via Autoencoders

ICC 2020 - 2020 IEEE International Conference on Communications (ICC), 2020
We provide unsupervised machine learning (ML) schemes based on autoencoders for unconstrained beamforming (BF) and hybrid BF in millimeter-waves (mmWaves). An autoencoder is a powerful unsupervised ML model, and it is used to reconstruct the input with a minimal error by finding a low-dimensional representation of the input. In this paper, we present a

mmWave for future public safety communications

Proceedings of the First CoNEXT Workshop on ICT Tools for Emergency Networks and DisastEr Relief, 2017
The technologies developed for the next generation of cellular networks (i.e., 5G) are potential enablers for future Public Safety Communication (PSC) systems. These will indeed need advanced communication techniques, capable of providing real-time, low-latency and reliable interactions in different scenarios (vehicular, aerial, unmanned) and different

Monostatic RCS reduction at mmWaves

2015 Asia-Pacific Microwave Conference (APMC), 2015
This article presents the design of planar dielectric non-absorptive surfaces for monostatic Radar Cross Section (RCS) reduction at mmWaves. The proposed planar surfaces are composed of only dielectric unit cells that are designed in such away to exhibit 0o reflection phases at 71GHz and 88GHz, respectively.

TCP dynamics over mmwave links

2017 IEEE 18th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2017
Due to massive available spectrum in the millimeter wave (mmWave) bands, cellular systems in these frequencies may provides orders of magnitude greater capacity than networks in conventional lower frequency bands. However, due to high susceptibility to blocking, mmWave links can be extremely intermittent in quality.

3D mmWave Channel Model Proposal

2014
There is growing interest in using millimeter wave (mmWave) frequencies for future access communications based on the enormous amount of available spectrum. To characterize the mmWave channel in urban areas, wideband propagation measurements at 73 GHz have recently been made in New York City.
