PDL Impact on Linearly Coded Digital Phase Conjugation Techniques in CO-OFDM Systems
O. S. Sunish Kumar, A. Amari, O. A. Dobre +1
We investigate the impact of polarization-dependent loss (PDL) on the linearly coded digital phase conjugation (DPC) techniques in coherent optical orthogonal frequency division mu…
Second-Order Perturbation Theory-Based Digital Predistortion for Fiber Nonlinearity Compensation
O. S. Sunish Kumar, A. Amari, O. A. Dobre +1
The first-order (FO) perturbation theory-based nonlinearity compensation (PB-NLC) technique has been widely investigated to combat the detrimental effects of the intra-channel Kerr…
A Spectrally Efficient Linear Polarization Coding Scheme for Fiber Nonlinearity Compensation in CO-OFDM Systems
O. S. Sunish Kumar, O. A. Dobre, R. Venkatesan +4
In this paper, we propose a linear polarization coding scheme (LPC) combined with the phase conjugated twin signals (PCTS) technique, referred to as LPC-PCTS, for fiber nonlinearit…
