BROADBAND SIGNAL GENERATING METHOD AND APPARATUS, AND DEVICE EMPLOYING SAME

摘要

A broadband signal generating method may comprise the steps of: combining at least two maps to estimate a high-band spectrum parameter from a reconstructed narrow-band signal; estimating high-band excitation signal with respect to the reconstructed narrow-band signal; generating a high-hand signal using the estimated high-band spectrum parameter and the estimated high-band excitation signal; and generating a broadband signal by synthesizing the reconstructed narrow-band signal and the high-band signal.
