What is decision feedback equalizer?
The Decision Feedback Equalizer (DFE) is a form of non-linear equalization which relies on decisions about the levels of previous symbols (high/low) to correct the current symbol. This allows the DFE to account for distortion in the current symbol that is caused by the previous symbols.

Decision Feedback Equalization (DFE)
What does an adaptive equalizer do?
An adaptive equalizer is an equalizer that automatically adapts to time-varying properties of the communication channel. It is frequently used with coherent modulations such as phase-shift keying, mitigating the effects of multipath propagation and Doppler spreading.
What are the modes of adaptive equalizer?
The examples of these ADAPTIVE EQUALIZERS are zero forcing equalizer, minimum mean square error equalizer, and desicion feedback equalizer.
