Abstract
We construct in this paper a Decision Feedback Equalizer (DFE) for a time-varying transmission system. The equalizer is imposed with a structure analogous to an Finite Impulse Response Basis Expansion Model (FIR-BEM). For this parametric equalizer, we compute its taps semi-blindly, following a Recursive Least Squares (RLS) approach. Simulation results confirm that the proposed algorithm is robust and can tolerate channel modeling errors.
