Abstract: The present disclosure provides a code generator for generating an {N′, K′} code for encoding and/or decoding data transmitted in a communication channel from an {N, K} code, wherein N and N′ are code lengths, K and K′ are code dimensions. The code generator is configured to shorten the {N, K} code to obtain an intermediate code, and to extend the intermediate code to obtain the {N′, K′} code. The present disclosure also provides a corresponding code construction method. Further, the present disclosure provides a device for encoding and/or decoding data transmitted in a communication channel, the device being configured to encode and/or decode the data based on an {N′, K′} code generated from the {N, K} code.

Abstract: Embodiments of the present application provide a decoding method and a decoding device. The decoding device receives a second code word, which is transmitted from an encoding device based on a first code word. The first code word is generated by the encoding device based on a first encoded data sequence. After determining that a second encoded data sequence based on the second code word is not a correct replica of the first encoded data sequence, the decoding device performs a series of code element update processes to determining the correct replica of the first encoded data sequence.
