摘要: The invention discloses a mismatched error estimation method and system for parallel sampling system. comprises the steps of acquiring an sequence output by when input quantity is single frequency calibrating signal at any phase; simulating to generate standard sinusoidal cosine with phase 0; inputting preset constant adaptive filter estimate parameter, weight coefficient corresponding each channel quantity; computing according quantity. According provided invention, mirror noise can be reduced, interference received decreased.
