Feedback-Aware Precoding for Millimeter Wave Massive MIMO Systems

Andreas Peter Burg, Reza Ghanaatian Jahromi

Millimeter wave (mmWave) communication is a promising solution for coping with the ever-increasing mobile data traffic because of its large bandwidth. To enable a sufficient link margin, a large antenna array employing directional beamforming, which is ena ...

PMU-Based ROCOF Measurements: Uncertainty Limits and Metrological Significance in Power System Applications

Mario Paolone, Asja Derviskadic, Guglielmo Frigo, Yihui Zuo

In modern power systems, the Rate-of-Change-of-Frequency (ROCOF) may be largely employed in Wide Area Monitoring, Protection and Control (WAMPAC) applications. However, a standard approach towards ROCOF measurements is still missing. In this paper, we inve ...

Overcoming the time-bandwidth limit

Camille Sophie Brès, Kosmas Tsakmakidis, Simon Julien Fabbri

We are so accustomed to the time-bandwidth limit that we often take it to be a fundamental relation that cannot be overcome. Contrary to this belief we here propose that the storage/delay time of a system can in fact be decoupled from the operating bandwid ...

Effects of erbium-doped fiber amplifier induced pump noise on soliton Kerr frequency combs for 64-quadrature amplitude modulation transmission

Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts, Fatemeh Alishahi, Lin Zhang, Ahmad Fallahpour, Amirhossein Mohajerin Ariaei

We experimentally investigate the effects of erbium-doped fiber amplifier induced pump noise on soliton Kerr frequency combs for 64-quadrature amplitude modulation (QAM) transmission. We find that the optical carrier-to-noise ratios (OCNRs) of the comb lin ...

Design rules for Unipolar Unicolor Coded Brillouin Optical Time Domain Analysis

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhisheng Yang, Simon Adrien Zaslawski, Zonglei Li

The performance of unipolar unicolor coded Brillouin optical time-domain analysis (BOTDA) is thoroughly studied, providing quantitative guidelines to design a distortion-free coded BOTDA system operating at maximum signal-to-noise ratio. ...

Pulse-Stream Models In Time-Of-Flight Imaging

Jean-Philippe Thiran, Yves Wiaux, Dimitris Perdios, Adrien Georges Jean Besson

This paper considers the problem of reconstructing raw signals from random projections in the context of time-of-flight imaging with an array of sensors. It presents a new signal model, coined as multi-channel pulse-stream model, which exploits pulse-strea ...

Lippmann waveguide spectrometer with enhanced throughput and bandwidth for space and commercial applications

Hans Peter Herzig, Mohammadreza Madi, Benedikt Guldimann, Philippe Giaccari

This article presents an innovative high spectral resolution waveguide spectrometer, from the concept to the prototype demonstration and the test results. The main goal is to build the smallest possible Fourier transform spectrometer (FTS) with state of th ...

Photonic chip-based soliton frequency combs covering the biological imaging window

Tobias Kippenberg, Junqiu Liu, Maxim Karpov, Martin Hubert Peter Pfeiffer, Anton Lukashchuk

Dissipative Kerr solitons (DKS) in optical microresonators provide a highly miniaturised, chip-integrated frequency comb source with unprecedentedly high repetition rates and spectral bandwidth. To date, such frequency comb sources have been successfully a ...
