Robustness and convergence of adaptive schemes in blind equalization

We 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.
