Problems solved by technology

However, since LDPC is a linear block code, when the code length of a single processing information is long, it will increase the difficulty of circuit implementation, and also greatly increase the consumption of logic resources, which seriously affects the performance of encoding and decoding.

Abstract

The embodiments of the present invention provide an encoding and decoding method and device. The encoding method includes: equally dividing input K-bit information into n blocks, where k1, k2, . . . , and kn are used to represent each block of information; combining a kith block of information with n-1 encoded code words Vi-1, Vi-2, . . . , and Vi-n+1 ki-1th, and ki-2th, . . . , and ki-n+1th blocks, to obtain a code word to be encoded, where when a sequence number of an encoded code word is smaller than or equal to 0, the encoded code word is history information; performing, by using an LDPC check matrix, encoding on the code word to be encoded, where a generated check bit and the kith block of information form an encoded code word Vi; and outputting encoded code words V1, V2, . . . , and Vn. The embodiments of the present invention are applied in encoding and decoding.

Description

technical field [0001] The present invention relates to the communication field, in particular to an encoding method, a decoding method, an encoding device, and a decoding device. Background technique [0002] In the high-speed information transmission system commonly used at present, it is usually necessary to perform FEC (Forward Error Correction, Forward Error Correction) coding on the information to be sent at the sending end, and correct the transmission link through the corresponding FEC decoder at the receiving end. errors in and output the required information. Among them, FEC refers to such a technology that the information is pre-processed according to a certain format before being sent, and then decoded according to a prescribed algorithm at the receiving end to find out and correct errors. [0003] With the development of high-speed information transmission systems, higher requirements are put forward for FEC technology. High-performance, high-flow, low-difficu...
