Decoding method, decoder, electronic equipment and storage medium

Abstract

The invention provides a decoding method, a decoder, electronic equipment and a storage medium, and the decoding method comprises the steps that a target component decoder executes at least one decoding process based on channel information; after the target component decoder determines that at least one decoding process is executed, a decoding result is obtained based on the last decoding process; wherein the primary decoding process comprises the following steps of: determining prior information by a target component decoder; based on the input channel information and the prior information determined by the target component decoder, posterior information corresponding to the target component decoder is output, the posterior information corresponding to the target component decoder is used for determining the prior information to be input of the second component decoder, and the prior information to be input of the second component decoder is used for determining the prior information to be input of the target component decoder. The second component decoder is a decoder except the target component decoder in the at least one component decoder. According to the decoding method, the decoder, the electronic equipment and the storage medium provided by the invention, decoding of the Turbo-like code with strong constraint and low code rate is realized.

Description

technical field [0001] The present invention relates to the field of digital signal processing, and in particular, to a decoding method, a decoder, an electronic device and a storage medium. Background technique [0002] When performing channel coding, the reliability of communication transmission can be guaranteed by adding redundant information. However, in actual communication systems, especially in satellite communication systems, the transmission distance is long, resulting in a low signal-to-noise ratio of the received signal. The channel coding technology with high coding gain is used to combat the strong interference caused by factors such as long-distance transmission. The Turbo-like code with strong constraints and low bit rate, as a low bit rate coding that can approach the Shannon limit, is suitable for long-distance transmission signals. [0003] Strongly constrained low-rate Turbo-like codes combine the low-rate structure of Hadamard codes with the high coding ...
