Adaptive filtering and periodic inputs: conditions for an exponential divergence
Adaptive filters find applications in many areas of signal processing and echo cancellation is one of them. It has been observed that, due to non-linearities inherent in the implementation, echo cancelers can diverge when their input is periodic. In this paper we examine the behaviour of adaptive filters in the presence of periodic inputs and provide a theoretical explanation and conditions for a potential exponential divergence.
