Nonlinear decision feedback equalization using RCPL network

In this paper, we introduce a nonlinear decision feedback equalizer (DFE) structure which decomposes the nonlinear equalization problem into feedback and feedforward parts, thus allows flexibility in the choice of suitable structures for a given problem and improves on the performance of the conventional DFE and the nonlinear equalizer proposed in [1]. We show that the given general structure for this DFE can be represented by a recurrent canonical piecewise linear (RCPL) network [2] and that it satisfies the dynamic properties given in [3].
