Abstract
A system and method are provided for feed-forward equalization (FFE) in a transmission system. The method accepts a serial stream of input digital data signals. For each input data signal, a temporal sequence of signals is generated. Each of the signals in the temporal sequence is selectively shaped. Shaping map include varying the degree of amplification, modifying the slew rate, or varying the time delay. The contributions of the selectively shaped signals in the temporal sequence are then selectively weighted, and a summed output signal is transmitted.
