Title:
LDPC CODING AND DECODING METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/216991
Kind Code:
A1
Abstract:
Disclosed in the present application are an LDPC coding and decoding method and a related device. The present application is applied to a wireless local area network system supporting 802.11 series protocols such as next generation Wi-Fi protocol of IEEE802.11ax, i.e., Wi-Fi 8, and can also be applied to a wireless personal local area network system based on UWB. The method comprises: performing low-density parity check (LDPC) coding on an information bit sequence according to a check matrix to obtain a first codeword; the check matrix conforming to a basis matrix, wherein the basis matrix satisfies one of the following: each row in the first two columns of the basis matrix at least comprises 1, or the first two columns of the basis matrix comprise regular alternating "1 0" and "0 1", and "1 1" exists between "1 0" and "0 1"; sending the first codeword. The check matrix conforms to the basis matrix, and the overall decoding convergence speed of the system can be accelerated.
