Abstract
Step-gain control is crucial for acoustic echo cancelers. Most double-talk detectors and step-gain estimators become unreliable in certain situations. In this contribution, we combine a step-gain estimation method with a double-talk detector by fuzzy logic. This control is robust and efficient while requiring only very little additional complexity
