SIGNAL DECODING METHOD AND DEVICE |
摘要 |
Embodiments of the present invention provide a method and device for decoding a signal. The method for decoding a signal includes: obtaining spectral coefficients of sub-bands from a received bitstream by means of 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 means of decoding and is in the sub-band with unsaturated bit allocation, so as to restore the spectral coefficient that has not been obtained by means of decoding; and obtaining a frequency domain signal according to the spectral coefficients obtained by means of decoding and the restored spectral coefficient. In the foregoing embodiments of the present invention, a sub-band with unsaturated bit allocation in a frequency domain signal may be obtained by classification, and a spectral coefficient that has not been obtained by means of decoding and is in the sub-band with unsaturated bit allocation may be restored, thereby improving signal decoding quality. |
