ABSTRACT:
Methods, system, and computer programs for compensating for jitter in a communication system are described. A transfer function of a transmission medium is measured and an output signal that results from propagating an input signal through the transmission medium is calculated. Data dependent jitter is determined in the output signal. In memory, compensated edge positions of the input signal are stored. The compensated edge positions are arranged such that the data dependent jitter causes edge positions of the output signal to move closer to ideal edge positions.
