Decision Feedback Blind Equalizer with Maximum Entropy
Vladimir R. Krstić, Z. Petrovic · 2005
In this paper we propose a solution of an unsupervised decision feedback equalizer (DFE) based on switching DFE structure and joint entropy maximization algorithms (JEM). In the blind mode it is the linear Godard's equalizer strongly supported by JEM type decorrelator and in the decision-directed mode the nonlinear equalizer with soft decision feedback
