Abstract
Method and system for communicating data between a transmitter and a receiver via a physical transmission medium interposed there between, wherein the transmitter outputs over the transmission medium towards the receiver, a predefined precursor signal followed by a target signal carrying data packet. Based on the precursor signal received at the receiver, estimated values of actual electrical parameters of the physical transmission medium are computed via a predetermined model of the physical transmission medium, wherein the computed estimated values of the electrical parameters are indicative of a distortion caused by the physical transmission medium on the predefined precursor signal outputted by the transmitter. The data packets originally outputted by the transmitter are estimated based on the computed estimated values of the actual electrical parameters and on the target signal received at the receiver.
