A library modeling the fiber-optic channel governed by nonlinear schrödinger equation, accompanied with TX and RX DSP chain implementation

Fiber-Optic Transmission Systems Modeling

This library models the single-pol and dual-pol fiber-optic channels governed by nonlinear Schrödinger equation (NLSE) and coupled NLSE, accompanied with TX and RX DSP chain implementation.

NLS equation is solved using split-step Fourier method in this library.

The TX and RX DSP chain module, for single-polarization, includes the following modules:

• Modulation
• RRC Pulse shaping
• Sampling
• Matched filtering
• Chromatic dispersion compensation
• Digital back-propgation
• Detection
• Demodulation

For dual-polarization systems, in addition to the modules above, the following modules are implemented:

• Polarization multiplexation and demultiplixation
• Radius-directed-equalization (RDE) -based multiple-input-multiple-output (MIMO) algorithm to compensate for the PMD

This library is under documentation!
