CODING, DECODING, CODING-DECODING METHOD, CODING-DECODING SYSTEM AND RELEVANT DEVICE

摘要

A coding, decoding, coding-decoding method, coding-decoding system and the relevant device are provided. The coding method includes: obtaining the corresponding amplitude vector and the length vector of the vector to be coded, ordering the amplitude vector and length vector according to the preset ordering rule obtaining the position index value according to the ordered amplitude vector and ordered length vector. A decoding method, coding-decoding system and device are provided.
