Abstract

The invention provides a forward error correction coding method, a forward error correction decoding method and a device thereof. The forward error correction coding method comprises the steps of filling stuffing materials in messages according to a preset code rule, dividing the messages which are filled with the stuffing materials into a plurality of data blocks with the same length, removing the stuffing materials from the data blocks according to the code rule and a redundancy correcting block generated from the data block, respectively confirming a cyclic redundancy check value of the redundancy correcting block and the data block without stuffing materials, adding the cyclic redundancy check value into the corresponding redundancy correcting block and the data block without stuffingmaterials, forming a forward error correction code by the redundancy correcting block and the data block without stuffing materials, creating a data frame according to the forward error correction code and sending the data frame to a receiving end, wherein the data frame comprises a frame header, the forward error correction code and a frame end. The bandwidth resources are saved by adopting the forward error correction coding method of the invention.

Description

technical field [0001] The embodiment of the present invention relates to communication technology, and in particular to a forward error correction coding method, a forward error correction decoding method and a device thereof. Background technique [0002] In related technologies, due to the influence of electromagnetic interference in the wireless transmission link, current surge in the electrical transmission link, and signal strength in the optical transmission link, it is very easy to cause a packet burst in the data link. Burst error, the typical feature of burst error is that the error phenomenon is concentrated in a certain segment of continuous data, and causes a high bit error rate of this segment of data. In severe cases, the bit error rate of burst errors can reach 10 -3 , that is to say, if the length of the message exceeds 1000 bytes, the average error rate of the message is 100%. Such a high bit error rate will lead to increasingly serious bit errors on the w...
