Abstract:
A method and apparatus for generating a four-level pulse amplitude modulation (PAM-4) optical signal are disclosed. The method of generating a PAM-4 optical signal may include outputting a PAM-4 electrical signal, generating a PAM-4 optical signal based on the PAM-4 electrical signal, extracting feature information of the PAM-4 electrical signal from the PAM-4 electrical signal, and generating a control signal to control an operation of generating the PAM-4 electrical signal based on the feature information.
