Leaky Zero-Forcing Adaptive Equalization
Jan W. M. Bergmans, Meijin Lin · IEEE Signal Processing Letters · 2004
Zero-forcing equalizer adaptation schemes are attractive because of their simplicity. We study their steady-state solution, and find that it is more poorly conditioned than that of least mean-square adaptation schemes. A simple yet effective solution to this problem, based on tap leakage, is proposed, analyzed, and exemplified for an idealized digital optical storage system.
