Abstract

The embodiment of the invention provides a decoding method and device, a decoder and a storage medium. The method comprises the following steps: carrying out grouped iterative decoding by adopting a first decoding method, and verifying a current grouped iterative decoding result after each grouped iterative decoding to obtain a target decoding result; wherein the first decoding method comprises an error correction decoding equation and a verification decoding equation. According to the decoding scheme provided by the embodiment of the invention, the check decoding equation is introduced into the error correction decoder, and the error correction performance of the decoding system is improved by reducing the coding rate.

Description

A decoding method, device, decoder and storage medium technical field The present invention relates to but not limited to communication field, be specifically related to a kind of decoding method, device, decoder and storage medium quality. Background technique [0002] In modern digital communication systems, channel coding and decoding are an important part. Due to channel fading, interference, noise Due to the influence of various factors such as sound, the transmission of data on wireless channels is usually unreliable. channel coding technology through The redundancy is added in a certain way to protect the data information and counteract the random distortion introduced by the wireless channel to the transmission signal. According to the receiver In known coding methods, the received signal is decoded using redundant information. Here, the role of channel coding is mainly reflected in The following two aspects: Error detection (error detection): Refers to...
