Abstract

In some disclosed embodiments, a Decision Feedback Equalizer (DFE) processes multiple symbols in parallel using a novel architecture that avoids violating a timing constraint. The DFE comprises Feed-Back (FB) filters that can be configured to equalizing nonlinear phenomena. Using a Look-Up Table (LUT)-based implementation, the FB filters may implement complex nonlinear functions at low hardware complexity, low latency and low power consumption. A LUT-based implementation of the FB filter supports adaptive FB filtering to changing channel conditions by updating LUT content.
