Wiener-Hammerstein model and its learning for nonlinear digital pre-distortion of optical transmitters [PDF]

Optics Express, 2020
We present a simple nonlinear digital pre-distortion (DPD) of optical transmitter components, which consists of concatenated blocks of a finite impulse response (FIR) filter, a memoryless nonlinear function and another FIR filter.
