Abstract
An apparatus for predicting an acceleration signal predicts an acceleration signal of an acceleration sensor installed on a vehicle for active noise control (ANC) and includes: a prediction module configured to train a predefined prediction algorithm to predict an acceleration signal after N samples compared to a point in time at which an acceleration signal is acquired by the acceleration sensor (N is a natural number), and to apply a reference acceleration signal acquired at a reference point in time to the completely trained prediction algorithm to generate a predicted acceleration signal after the N samples compared to the reference point in time; and an ANC module configured to perform ANC on the basis of the predicted acceleration signal generated by the prediction module.
