Method and device for error correction and verification of communication data packets

Abstract

A communication data packet error correction method and device, the communication data packet includes an initial data packet and an error correction data packet, wherein the initial data packet includes N initial data blocks, and the N initial data blocks include N-1 first A valid data block and a first verification data block, the error correction data packet includes N error correction data blocks corresponding to the N initial data blocks one by one, and the receiving end performs a check on the first valid data block according to the first verification data block The first verification operation, if the first verification is correct, then process the first valid data block, otherwise, the receiving end performs error correction operation on the initial data packet according to the error correction data packet to obtain the correction data packet, the correction data The packet includes N-1 second valid data blocks and a second verification data block, and the receiving end performs a second verification operation on the second valid data block according to the second verification data block, and if the second verification is correct, then Process the second valid data block; otherwise, the receiving end discards and requests to resend the communication data packet.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for error correction and verification of communication data packets. Background technique [0002] In the communication method, usually after each valid data block, the corresponding error correction data block is appended to realize the verification and error correction of the current valid data block, and the valid data block and the corresponding error correction data block Together they form a communication data block, and a series of communication data blocks together form a communication data packet. However, during the data transmission process of the above communication data packet, if an error occurs in a certain error correction data block, the error correction data block will perform an error correction operation on the corresponding valid data block, resulting in an error in the originally correct valid data block. As a result, communication fails. Con...
