A combined regular-logarithmic perturbation method for signal-noise interaction in amplified optical systems [PDF]

open access: yes, 2009
We present a novel perturbation method for the nonlinear Schrödinger equation (NLSE) that governs the propagation of light in optical fibers. We apply this method to study signal-noise interactions in amplified multispan fiber-optic systems.

Minimum BER Criterion Based Robust Blind Separation for MIMO Systems [PDF]

open access: yes, 2019
In this paper, a robust blind source separation (BSS) algorithm is investigated based on a new cost function for noise suppression. This new cost function is established according to the criterion of minimum bit error rate (BER) incorporated into maximum
