Abstract
The present invention relates to a system and method for improving the waveform at a receiver. More specifically, the present invention relates to a system adapted to modify at least one signal in anticipation of channel attenuation and delay. The present invention comprises a memory adapted to store at least one coefficient that is pre-determined based on at least one expected degradation characteristic of a channel; and a pre-emphasizer communicating with at least the memory and the channel, and adapted to modify the at least one signal using the at least one coefficient prior to transmission of the at least one signal over the channel, compensating for the at least one expected degradation characteristic.
