Photonic Digitization With Differential Encoding Based on Orthogonal Vector Superposition
Published 2019-01-01Get full textIn this paper a novel photonic digitization scheme with differential encoding based on orthogonal vector superposition (OVS) is proposed and demonstrated. A phase modulator (PM) and two delay-line interferometers (DLIs) with π/2 difference in bias phase are employed to generate...

Channel Modeling and Performance Analysis of Modulating Retroreflector FSO Systems Under Weak Turbulence Conditions
Published 2017-01-01Get full textThis paper presents the fading channel of double-pass modulating retroreflector free-space optical systems under weak turbulence conditions that can be modeled by the distribution of the weighted product of two correlated Lognormal random variables. We first show the proposed channel model through u...
