Abstract Coherent optical orthogonal frequency division multiplexing (CO-OFDM) system is susceptible to nonlinear effects because of its intrinsic high peak-to-average ratio (PAPR). In this paper, two methods based on discrete Fourier transform sprea

In fiber-wireless integration systems, it is valuable to investigate whether digital subcarrier multiplexing (SCM) signal is effective in improving nonlinear tolerance against photodiode (PD) saturation compared to single-carrier (SC) signal. For a f

The transmission of constant-envelope orthogonal frequency division multiplexing (CE-OFDM) signals, based on electrical phase modulation, was shown to improve the tolerance to noise and the nonlinearity introduced by light-emitting diodes (LEDs) in v

We present a complete analysis of the Schelling dynamical system of two connected neighborhoods, with or without population reservoirs, for different types of linear and nonlinear tolerance schedules. We show that stable integration is only possible

We show more than 1 dB of additional SNR improvement by deploying perturbation-based nonlinearity DSP at the receiver side for 30 GBaud dual-polarization 16-QAM transmission over a 2560 km link with a mid-link optical phase conjugation.

We investigate the CCDM performance in subcarrier-multiplexing systems and show the reduced nonlinear tolerance with conventional CCDM implementation. A dimension-interleaved (DI) CCDM scheme is evaluated for fiber nonlinearity mitigation.
