Design of fiber amplifier based communication systems using a Volterra series approach

Nonlinear Electrical Compensation for the Coherent Optical OFDM System

“…Peddanarappagari and Brandt-Pearce have shown that at a higher input signal power, for a fixed input pulse width, the detector output pulse width increases with higher peak pulse power and makes the system more sensitive to nonlinearity distortion [9]. As a result, the low order nonlinear equalizer with a short memory span is not able to fully compensate the nonlinear channel.…”

“…The Volterra model is a widely used nonlinear signal processing tool [7]. It has been used to model the optical communication system nonlinearity [8][9][10][11][12]. The Volterra model is also used to mitigate nonlinearity effects in optical communication systems [13] and design equalizers for optical systems with OOK and PSK modulation [6,11,[14][15][16]].…”

“…9 shows the normalized mean square error (NMSE) of the different channel models. NMSE quantizes the difference between model output and the actual system output.…”

A Principal Investigation of the Group Velocity Dispersion (Gvd) Profile for Optimum Dispersion Compensation in Optical Fibers: A Theoretical Study

“…Analytical solutions are so excellent to show nature of phenomenon in propagation. For handling of NLS equation in the past the Volterra series was used [21][22][23][24][25][26][27]. Since two or three terms of this series completely describe light propagation and show some of important phenomenon in fibers, we concentrate on this method for analytical solution.…”
