Abstract:
An encoding method, a decoding method, an encoding apparatus, a decoding apparatus, a transmitter, a receiver, and a communications system, where the encoding method includes dividing a to-be-encoded time-domain signal into a low band signal and a high band signal, performing encoding on the low band signal to obtain a low frequency encoding parameter, performing encoding on the high band signal to obtain a high frequency encoding parameter, obtaining a synthesized high band signal; performing short-time post-filtering processing on the synthesized high band signal to obtain a short-time filtering signal, and calculating a high frequency gain based on the high band signal and the short-time filtering signal.

Claim (Index 12):
The encoding apparatus of  claim 11 , wherein the instructions further cause the processor to be configured to perform, using a first-order, filtering processing on the synthesized high band signal that has been processed by the pole-zero filter, a z-domain transfer function of the first-order filter being H t (z)=1\u2212\u03bcz \u22121 , and the \u03bc being a preset constant.
