Abstract

With a view toward properly combining a fundamental echo with a harmonics echo according to the quality of a signal, the ratio between two frequency components of the fundamental echo is determined (704), and the ratio between two frequency components of the harmonics echo is determined (702). Further, a component ratio between a fundamental component and a harmonics component in an echo receive signal is adjusted based on these two ratios (706, 708).
