Blind Non-linear Equalization Using Variational Autoencoders
Background In digital communication the goal is to send information, usually represented by bits, from A (transmitter, Tx) to B (receiver, Rx). At some point in this process, the bits “meet” the physical world in the form of a channel. In optical communication, light from a laser diode is used to carry the information that travels through an optical fiber and is then detected at receiver using a photodiode. However, the optical fiber channel does not perfectly pass on the light as it will be attenuated and distorted the longer the light travels....
