OPTICAL OFDM RECEIVER AND OPTICAL SIGNAL RECEIVING METHOD THEREOF

摘要

PURPOSE: An optical OFDM receiver and optical signal receiving method thereof are provided to solve a non-linear which is caused by an optical modulator and an optical channel. CONSTITUTION: An optical down converter(210) converts an optical signal into an electrical signal. A non-linear compensation unit(220) filters the electrical signal for compensating the influence of distortion added to the optical signal when optical modulating of a transmitter.
