ABSTRACT:
An echo cancellation apparatus (20) and method involves an operation AEPR for analyzing echo path response and thereafter an operation CR for configuring an adaptive FIR filter (52). The configuration of the adaptive filter (52) advantageously results in only a range of filter taps and coefficients between two specified tap endpoints being involved in filter multiplication, addition, and storage during the echo cancellation operation.
