Simultaneous harvest-and-transmit ambient backscatter communications under Rayleigh fading [PDF]
EURASIP Journal on Wireless Communications and Networking, 2019 Les communications à rétrodiffusion ambiante sont un paradigme émergent et un catalyseur clé de la connectivité omniprésente des appareils sans fil de faible puissance. Il est principalement bénéfique dans l'Internet des objets (IoT) et dans les situations où les capacités de calcul et de connectivité s'étendent aux capteurs et aux appareils miniatures

Open Source SDR Frontend and Measurements for 60-GHz Wireless Experimentation
IEEE Access, 2015 This paper aims to make 60-GHz experimentation possible for a wider range of research groups. We do this by describing a low-cost front-end that can be used in combination with any baseband processing platform.

Rayleigh Backscattering Noise Alleviation in Long-Reach Ring-Based WDM Access Communication
IEEE Access, 2020 In the paper, we propose and design a ring-topology wavelength-division-multiplexing (WDM) access network for long-reach signal transmission. Here, the new central office (CO) and optical network unit (ONU) modules are designed to construct the ring ...

Rayleigh backscattering in a fiber gyroscope with limited coherence sources [PDF]
Journal of Lightwave Technology, 1983 Noise due to temporal fluctuations of Rayleigh baekscattered light in fiber-optical gyroscopes is studied experimentally with various sources whose coherence length is less than the fiber length. The reduction of the coherent fraction of backscattered light and its fluctuation frequencies with reduced source coherence is demonstrated and fit to an ...

Hybrid WDM FSO Fiber Access Network With Rayleigh Backscattering Noise Mitigation
IEEE Access, 2020 In the paper, we present and investigate an integrated wavelength-division-multiplexing (WDM) free space optical (FSO) fiber access network for 51 km long-reach connection. Here, the proposed network architecture also can mitigate Rayleigh backscattering

25-GHz-Spaced DWDM-PON With Mitigated Rayleigh Backscattering and Back-Reflection Effects
IEEE Photonics Journal, 2013 A novel 25-GHz-spaced dense wavelength-division multiplexing passive optical network (DWDM-PON) is proposed to improve the utilization of wavelength resource and mitigate the Rayleigh backscattering (RB) and back-reflection effects.

Tunable Raman fiber laser induced by Rayleigh back-scattering in an ultra-long cavity [PDF]
Journal of the European Optical Society-Rapid Publications, 2011 We report an ultra-long Raman laser with a 46 km fiber length that behaved as a Rayleigh back-scattering–based optical feedback. The laser was tunable from 1550 nm to 1571 nm (3 dB bandwidth) with the insertion of an optical grating filter.
