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 27):
The decoder of  claim 25 , wherein the current frame comprises second sub-band comprising a plurality of second spectral coefficients, and wherein the processor is further configured to:\n obtain a second average quantity of allocated bits per spectral coefficient for the second sub-band; and avoid reconstruction of the second spectral coefficient when the second average quantity of allocated bits per spectral coefficient is greater than or equal to the classification threshold.
