 * Numerical models to simulate optical transmitters, nonlinear propagation over optical fibers, and optical receivers.
 * CPU and GPU-based implementations of the [*split-step Fourier Method*](https://en.wikipedia.org/wiki/Split-step_method) to simulate polarization multiplexed WDM transmission.

+* Standard digital signal processing (DSP) blocks employed in coherent optical receivers. For most of the cases, [Numba](https://numba.pydata.org/) is used to speed up the core functions.
 * Tools to evaluate transmission performance metrics such as *bit-error-rate* (BER), *symbol-error-rate* (SER), *mutual information* (MI), *generalized mutual information* (GMI).
