MIMO DFE Equalization for High-Speed Chip-to-Chip Communication

In this contribution, we present a multipleinput multiple-output (MIMO) decision feedback equalizer (DFE) for high-speed chip-to-chip communication. We derive an elegant closed-form expression for the minimum mean square error (MMSE) equalization filters and show that the application of MIMO DFE allows to significantly improve the reliability of transmitting high data rates over low-cost electrical interconnects.
