A Joint OSNR and Nonlinear Distortions Estimation Method for Optical Fiber Transmission System
IEEE Photonics Journal, 2018 In this paper, we propose and demonstrate a joint optical signal-to-noise ratio (OSNR) and a nonlinear distortions estimation method. The OSNR is calculated by considering either the link parameters or the correlation operations of the training symbols ...

Nonlinear perturbation theory with halo bias and redshift-space distortions via the Lagrangian picture [PDF]
Physical Review D, 2008 The nonlinear perturbation theory of gravitational instability is extended to include effects of both biasing and redshift-space distortions, which are inevitable in predicting observable quantities in galaxy surveys.

Polarization shaping for control of nonlinear propagation [PDF]
, 2016 We study the nonlinear optical propagation of two different classes of space-varying polarized light beams -- radially symmetric vector beams and Poincar\'e beams with lemon and star topologies -- in a rubidium vapour cell.

Hardware Design of a High Dynamic Range Radio Frequency (RF) Harmonic Measurement System
Instruments, 2018 Radio frequency (RF) circuit elements that are traditionally considered to be linear frequently exhibit nonlinear properties that affect the intended operation of many other RF systems. Devices such as RF connectors, antennas, attenuators, resistors, and

Minimalistic System of Characteristics of Non-linear Baseband Pulse Devices and Its Measurement
Известия высших учебных заведений России: Радиоэлектроника, 2023 Introduction. The general system of parameters, including compression points and intersection points of various harmonics, is unsuitable for devices operating under the influence of baseband pulses (for example, before the modulator in the transmitter ...

Nonlinearities of GaAlAs lasers - Harmonic distortion [PDF]
IEEE Journal of Quantum Electronics, 1980 Narrow stripe lasers ( 2-6 \mu m) and transverse junction lasers exhibit excellent linearity. The dependence of relative second-and third-harmonic distortion is investigated as a function of modulation frequency and modulation current. Relative second- and third-harmonic distortion of -50 and -70 dB is observed for an optical signal of 4 mW p-p ( f_{m}

, 1948 In the present work, we apply the asymptotic homogenization technique to the equations describing the dynamics of a heterogeneous material with evolving micro-structure, thereby obtaining a set of upscaled, effective equations.

Superluminescent damping of relaxation resonance in the modulation response of GaAs lasers [PDF]
, 1983 It is demonstrated experimentally that the intrinsic modulation response of injection lasers can be modified by reducing mirror reflectivities, which leads to suppression of relaxation oscillation resonance and a reduction of nonlinear distortions up to ...

Compensation for phase distortions in nonlinear media by phase conjugation [PDF]
, 1980 We demonstrate theoretically that the distortion-correction property of phase-conjugate beams propagating in reverse through aberrating media is also operative when the indices of refraction of the media depend on the intensity.

Memory Effects of High-Power Amplifiers in LSTM-Based Vehicular Channel Estimation
IEEE Access, 2023 The upcoming sixth generation (6G) of wireless communication systems is expected to enable a wide range of new applications in vehicular communication. However, the use of multicarrier-based modulation in vehicular communication introduces challenges due
