Abstract: A method includes transmitting, by a transmitter and over a transmit channel to a remote device, a signal that includes a plurality of signal points and receiving, by a receiver and over a receive channel from the remote device, a response signal that includes a plurality of response points corresponding to the plurality of signal points. The method also includes adjusting the plurality of signal points of the signal until logical values of the plurality of response points invert to produce an adjusted signal, estimating, based on the adjusted signal, a pulse response of the transmit channel, and applying equalization in the transmitter based on the estimated pulse response to reduce an effect of the pulse response on the signal.
