Abstract

In one aspect, the present invention is a system and technique that provides for the systematic development or implementation of codes that increase the robustness of systems employing, for example, PAM-n transmission techniques. The system and technique of this aspect of the invention eliminate, minimize, reduce or limit transitions between extreme signaling levels. As a result, the slew rate employed and/or required by the transmitter may reduce crosstalk and intersymbol interference, and provide for wider “eye” openings from the perspective of the receiver.
