Abstract
Systems and methods related for duo-binary transceivers with adaptive channel equalization are described. An example method for adapting a channel between a first duo-binary transceiver and a second duo-binary transceiver, different from the first duo-binary transceiver, where the transmitter includes a feed-forward equalizer (FFE), is described. The method includes, at a receiver associated with the second duo-binary transceiver, selectively processing information at a given time from only an upper eye or a lower eye of a received duo-binary signal to determine updated coefficients for the feed-forward equalizer (FFE) of the transmitter associated with the first duo-binary transceiver. The method further includes using a backchannel between the transmitter and the receiver, sending the updated coefficients to the transmitter. The method further includes transmitting duo-binary signals that are equalized using the updated coefficients for the FFE of the transmitter associated with the first duo-binary transceiver.
