Title:
CODING AND DECODING METHODS, COMMUNICATION APPARATUS, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/237850
Kind Code:
A1
Abstract:
Coding and decoding methods, a communication apparatus, and a system. In the coding method: a coding apparatus performs coding on first data by means of a coding model, and obtains N pieces of coded data, N being an integer greater than two; said apparatus performs decorrelation on the N pieces of coded data, and obtains N pieces of decorrelated coded data, a portion or all of the N pieces of decorrelated coded data able to be used for determining second data, the second data being used for recovering third data, and the third data being the first data or having a degree of similarity to the first data that is greater than set threshold; and said apparatus sends the N pieces of decorrelated coded data. The N pieces of decorrelated coded data are mutually independent and not correlated, and so a decoding apparatus can recover, on the basis of the N pieces of decorrelated coded data, the third data which has a degree of similarity to the first data that is greater than the set threshold, and thereby the decoding apparatus can receive a portion or all of the N pieces of decorrelated coded data according to a bandwidth resource usable by said decoding apparatus, and a bandwidth adaptation capability for encoded data is improved.
