What is DFE (Decision-Feedback Equalization)?

The Decision Feedback Equalizer (DFE) depends on choices about the degrees of previous symbols to address the current symbol. This permits the DFE to represent distortion in the current symbol that is brought about by the previous symbols. Its fundamental benefit over linear equalizers is the capacity to cancel inter-symbol interference (ISI) without intensifying the noise. The DFE administrator permits to approve hardware DFE designs and examine their impacts on eye openings.
