Transmitter Pre-emphasis and Adaptive Receiver Equalization for Duobinary Signaling in Backplane Channels

In this paper, an adaptive equalization technique of a multi-gigabit channel using duobinary signaling is proposed. Both the receiver and transmitter are equalized and implemented using ADS. The results show that the duobinary signaling performs better than NRZ at half of the bandwidth. The algorithm was tested in a Tyco XAUI-FR4 backplane.
