Nonlinear blind equalization method for PAM-4 signal transmission

摘要

The present invention relates to a nonlinear blind equalization method for transmitting a PAM-4 signal, and the present invention relates to a method for transmitting linear and nonlinear signals during multi-level signal transmission for transmitting a PAM-4 signal in an intensity modulation and direct detection (IM/DD) optical network. A nonlinear blind equalization method capable of reducing distortion is provided.
