Robustness and convergence of adaptive schemes in blind equalization

Rupp, MarkusSayed, Ali H.2017-12-192017-12-192017-12-19199610.1109/ACSSC.1996.600871https://infoscience.epfl.ch/handle/20.500.14299/143171We pursue a time-domain feedback analysis of adaptive schemes with nonlinear update relations. We consider commonly used algorithms in blind equalization and study their performance in a purely deterministic framework. The derivation employs insights from system theory and feedback analysis, and it clarifies the combined effects of the step-size parameter and the nature of the nonlinear functional on the convergence and robustness performance of adaptive schemes.Robustness and convergence of adaptive schemes in blind equalizationtext::conference output::conference proceedings::conference paper
