Abstract

This invention describes a statistical adaptive-filter controller for digital acoustic echo control in hands-free telephones for achieving more consistent echo cancellation results (i.e. higher output signal quality) and simpler realizations of AEC units. The improvement using the simple statistical adaptive-filter controller is accomplished by optimizing a joint control of an echo canceller and a postfilter.
