Abstract

The invention provides a universal decoding method and device, equipment and a storage medium, and the method comprises the steps: receiving a to-be-decoded target code word, and grouping the target code word into decoding blocks; according to the decoding block, a decoding result corresponding to the target code word is output through a target universal decoder, and the decoding result is a decoding bit; wherein the target universal decoder is obtained by training a convolutional neural network from a codeword training set corresponding to multiple code patterns and multiple code rates, and the convolutional neural network is used for representing a decoding network. The method provided by the invention is high in decoding flexibility.

Description

technical field [0001] The embodiments of the present application relate to the technical field of decoding, and in particular, relate to a general decoding method, device, device, and storage medium. Background technique [0002] Channel coding and decoding aim to improve the reliability of information transmission and are key steps in wireless communication systems. Common channel coding methods include block codes, convolutional codes, and polar codes. For example, the control channel information in the LTE system is coded with convolutional codes, and the control channel in 5G enhanced mobile broadband (eMBB) scenarios is coded with polar codes. . Corresponding decoding methods include Viterbi decoding (ie, Viterbi decoding), SC decoding algorithm, and channel decoding algorithm based on neural network. [0003] Among them, the Viterbi decoding algorithm is actually a maximum likelihood decoding method for convolutional codes, that is, the output codeword of the Viterb...
