An adaptive equalizer for error free 40GbE data transmission on 40 inch high-speed backplane channel

This paper proposes the structures and algorithms for the adaptive equalizer that are required to allow high speed signaling over 40 Gb/s across a backplane channel. The proposed adaptive DFE has a fast convergence and low computational complexity. Simulations with a 40 Gb/s show that our adaptive equalizer can meet the IEEE 802.3ba requirement for backplane strip line up to 40 inches.
