AI Technical Summary

Technical Problem

How to design LDPC codes suitable for the IEEE 802.11bn standard to improve the transmission reliability of wireless transmission systems while reducing implementation complexity.

Method used

The LDPC code with a code length of 3888 bits is adopted. Based on the existing parity-check matrix with a code length of 1944 bits, the provided LDPC code parity-check matrix is ​​used for encoding and decoding processes. It supports code rates of 5/6, 3/4 and 2/3. The actual encoding matrix is ​​formed by expanding the parent matrix, which reduces the complexity of the existing encoding and decoding modules.

Benefits of technology

It achieves stronger error control performance and reduced implementation complexity, and is suitable for wireless LAN communication with the 802.11bn standard.

Abstract

The application relates to the technical field of wireless communication, in particular to a communication method, device and readable storage medium in a wireless local area network, the method comprising: an information bit sequence is acquired by a sending end; the information bit sequence is encoded based on a check matrix of an LDPC code to obtain a code word, the code length of the LDPC code is 3888 bits, and the check matrix of the LDPC code is as shown in the embodiment; and the code word is sent. By adopting the application, stronger error control performance can be obtained, and the implementation complexity can be reduced. The application supports IEEE series protocols, such as IEEE 802.11bn / UHR protocols, IEEE 802.15 / UWB protocols, IEEE 802.11bf / sensing protocols or integrated millimeter wave / IMMW protocols. The application can also support star flash / spark link / nearlink standard protocols.
