Experimental characterization of nonlinear interference noise as a process of intersymbol interference [PDF]

open access: yesOptics Letters, 2018
We demonstrate a method for experimentally characterizing the second order statistics of nonlinear interference noise (NLIN) as an intersymbol interference (ISI) process. The method enables measurement of the properties of high-order ISI coefficients, which have been largely overlooked in the past.

PSO Algorithm on PAPR Reduction Performance of Asymmetrically Clipped Optical‐OFDM

open access: yesApplied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.
This research presents a novel hybrid optimization framework combining artificial neural networks (ANN) and particle swarm optimization (PSO) to mitigate the high peak‐to‐average power ratio (PAPR) in asymmetrically clipped optical‐orthogonal frequency division multiplexing (ACO‐OFDM) systems. While conventional PTS effectively reduces PAPR, it suffers

Insights Into Modulation and Coding Scheme in Mobile Communication

open access: yesDiscrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.
With the growing demand for mobile communications and the advancement of technology, reducing energy consumption has become a critical challenge. Overservice, which leads to unnecessary energy waste, is attracting significant attention from both academia and industry. An optimized modulation and coding scheme (MCS) can reduce the energy consumption per

Bifurcation, Chaotic Behavior, Sensitivity Analysis, and Traveling Wave Solutions of the Nonlinear Telecommunication Model Through Transmission Lines

open access: yesDiscrete Dynamics in Nature and Society, Volume 2026, Issue 1, 2026.
This paper explores a nonlinear telecommunication transmission line model with the incorporation of the M‐truncated fractional derivative, providing memory‐dependent effects that go beyond the classical nonlinear transmission line models. The Hamilton–Jacobi and Jacobian dynamical frameworks are, for the first time, utilized in this fractional ...
