An algorithm-independent burst-free adaptive hybrid

This paper presents a structural solution to the bursting phenomena in adaptive hybrids. An algorithm-independent burst-free adaptive echo canceler is developed by introducing a stand-by adaptive filter in a single adaptive hybrid system. The purpose of this filter is to cancel out the pole(s) of the closed-loop characteristic equation, which, generally, lead to the bursting phenomena in adaptive systems with feedback. Several simulations examples are presented in this paper to demonstrate the superiority of the new configuration under the different conditions that would normally cause bursting, including practical situations where we have actual speech signals.
