Title:
ENCODING METHOD AND APPARATUS, AND DECODING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/036634
Kind Code:
A1
Abstract:
An encoding method and apparatus, and a decoding method and apparatus. The encoding method comprises: a transmitting end acquires a first bit sequence, and then performs LDPC encoding on the first bit sequence on the basis of a check matrix to obtain a second bit sequence. Correspondingly, a receiving end receives the second bit sequence, and then performs LDPC decoding on the second bit sequence on the basis of the check matrix to obtain K information bits. The first bit sequence comprises K information bits, the second bit sequence comprises M check bits, and K and M are both positive integers. The check matrix is obtained on the basis of a first basis matrix. The first basis matrix corresponds to a second basis matrix. The second basis matrix comprises the following elements: 0, 1 and 2. Elements 1 in the second column of the check part in the second basis matrix and elements 2 in the first column of the check part are in the same row, and the number of elements 1 in the second column is less than or equal to the number of elements 2 in the first column. A new LDPC code is introduced in bias source scenarios, so that the decoding performance can be effectively improved.
