Abstract:
A method and device for decoding a signal, where the method for decoding the signal includes obtaining spectral coefficients of sub-bands from a received bitstream by decoding, classifying sub-bands in which the spectral coefficients are located into a sub-band with saturated bit allocation and a sub-band with unsaturated bit allocation, performing noise filling on a spectral coefficient that has not been obtained by decoding and is in the sub-band with unsaturated bit allocation to restore the spectral coefficient that has not been obtained by decoding, and obtaining a frequency domain signal according to the spectral coefficients obtained by decoding and the restored spectral coefficient. Therefore, a sub-band with unsaturated bit allocation in a frequency domain signal may be obtained by classification, thereby improving signal decoding quality.

Claim (Index 22):
The decoder of  claim 20 , wherein none of the spectral coefficients are decodable by the decoder, and wherein wherein the processor being configured to reconstruct at least some of the spectral coefficients to generate the reconstructed spectral coefficients comprises the processor being configured to reconstruct all of the spectral coefficients to generate the reconstructed spectral coefficients.
