ABSTRACT:
A method and apparatus for echo cancelling linear and nonlinear echo components from a received signal by temporally and spatially separating the overall echo canceller into a fast, transversal filter based linear echo canceller which quickly cancels the linear echoes and a slow, look-up table based nonlinear echo canceller which cancels the nonlinear echo components.
