Abstract
A receiver of an optical communication system includes an organic photoelectric conversion device configured to convert optical signals received from a transmitter into an electrical signal; and a demodulator configured to input the electrical signal to a trained artificial neural network and demodulate the electrical signal based on an output of the trained artificial neural network.
Claims20
A method, comprising:
- equalizing signals at a transmitter to reinforce a particular wavelength band associated with a reception characteristic of an organic photoelectric conversion device of a receiver, based on a particular equalization parameter;
- modulating the equalized signals at the transmitter;
- driving the modulated equalized signals at the transmitter to a light source to be transmitted as an optical signal;
- receiving, at the transmitter, a signal to interference and noise ratio (SINR) estimated by the receiver subsequently to the optical signal being transmitted from the light source and being received and demodulated by the receiver;
- and
- adjusting, at the transmitter, the particular equalization parameter based on the received SINR.
