Improved MMSE Algorithm for DFE Optimization
The signal in channels with high-speed designs is attenuated by channel loss, inter-symbol interference, jitter, noise and crosstalk. The main way to recover the signal is by using equalizations, such as Feed-Forward Equalizer, Continuous Time-Linear Equalizer and Decision Feedback Equalizer (DFE). One of the important problems with high-speed design and channel simulations is developing fast optimization algorithms for each equalizer, as each additional tap increases the cost of the chip. The paper proposes a new efficient optimization of DFE for high-speed links. Mathematical formulation of the optimization is discussed. Different test results are given for comparison purposes.
