Abstract
A method of generating a wideband signal may include estimating a high-band spectrum parameter from a reconstructed narrowband signal based on a combination of at least two mapping schemes; estimating a high-band excitation signal based on the reconstructed narrowband signal; generating a high-band signal based on the estimated high-band spectrum parameter and the estimated high-band excitation signal; and generating a wideband signal by synthesizing the reconstructed narrowband signal with the high-band signal.
