Fiber nonlinearity-induced penalty reduction in CO-OFDM by ANN-based nonlinear equalization.
Elias Giacoumidis,Son Thai Le,Mohammad Ghanbarisabagh,Mary E. McCarthy,Ivan Aldaya,Sofien Mhatli,Mutsam A. Jarajreh,Paul Anthony Haigh,Nick Doran,Andrew D. Ellis,Benjamin J. Eggleton +10 more
TL;DR: An enhanced performance by up to ∼2 dB in Q-factor compared to the inverse Volterra-series transfer function NLE leads to a breakthrough in the efficiency of ANN.
Journal ArticleDOI
Fiber Nonlinearity Equalizer Based on Support Vector Classification for Coherent Optical OFDM
TL;DR: A support vector machine (SVM)-based classification nonlinear equalizer (NLE) is demonstrated, for the first time, in coherent optical orthogonal frequency-division multiplexing (CO-OFDM).

TL;DR: A fast Newton-based support vector machine (N-SVM) nonlinear equalizer (NLE) is experimentally demonstrated, for the first time, in 40 Gb/s 16-quadrature amplitude modulated coherent optical orthogonal frequency division multiplexing at 2000 km of transmission.

TL;DR: A novel versatile digital signal processing (DSP)-based equalizer using support vector machine regression (SVR) is proposed for 16-quadrature amplitude modulated (16-QAM) coherent optical orthogonal frequency-division multiplexing and experimentally compared to traditional DSP-based deterministic fiber-induced nonlinearity equalizers (NLEs).
Journal ArticleDOI
Performance evaluation of an IMDD optical OFDM-CDMA system
TL;DR: Results show that OFDM-OCDMA with multiple users has similar performance to single-user conventional OOFDM for low transmitted powers.
