Physical Layer Security Based on Chaotic Spatial Symbol Transforming in Fiber-Optic Systems
Published 2018-01-01Get full textWe propose a chaotic spatial symbol transforming encryption method for enhancing the physical layer security in fiber-optic systems based on space-division multiplexed (SDM) transmission. The designed 3-D chaotic sequences are used to scramble the real and imaginary part of quadrature amplitude modu...

Distributed Compensation With Parallelizability for Polarization Mode Dispersion Based on Learned Digital Backpropagation
Published 2025-01-01Get full textThis study proposes a learned digital backward propagation (LDBP) algorithm that performs a distributed compensation of polarization mode dispersion (PMD) in parallel. The proposed LDBP algorithm uses the regular perturbation theory of a fiber-optic nonlinear Schrödinger equation to creat...

Tailoring heat-resistant phases with strengthening effects by compound additions of zirconium, yttrium and silicon in dilute Al-Sc-(Zr)-(Y)-(Si) alloys
Published 2025-07-01Get full textHeat resistance aluminum alloys serving within 300–400 °C temperature range are prominently required due to lightweight design and extreme serve condition in aerospace and military fields. Dispersoid particles precipitated in Al–Sc system alloys possess preferential thermal stability, however, unsat...
