A Novel Decision Feedback Equalization Structure for Nonlinear High-Speed Links

IEEE Access, 2020
As the degree of nonlinearity in high-speed links becomes more and more serious, traditional decision feedback equalization (DFE) which is based on linear time-invariant assumption can no longer eliminate the inter-symbol interference effectively.
