Abstract
Official abstract text for this publication.
In a pulse encoding and decoding method and a pulse codec, more than two tracks are jointly encoded, so that free codebook space in the situation of single track encoding can be combined during joint encoding to become code bits that may be saved. Furthermore, a pulse that is on each track and required to be encoded is combined according to positions, and the number of positions having pulses, distribution of the positions that have pulses on the track, and the number of pulses on each position that has a pulse are encoded separately, so as to avoid separate encoding performed on multiple pulses of a same position, thereby further saving code bits.
First claim
Opening claim text (preview).
What is claimed is: 1. A pulse encoding method comprising: determining, by a speech pulse encoder, pulses that are on T tracks and required to be encoded, wherein T is an integer greater than or equal to 2; separately collecting, by the speech pulse encoder, according to positions, statistics about a pulse that is on each track and required to be encoded, to obtain the number N t of positions that have pulses on each track, distribution of the positions that have pulses on the…
