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

Abstract

Provided are a method and device for error correction and calibration of communication data packets. The communication data packets comprise an initial data packet and an error correction data packet, wherein the initial data packet comprises N initial data blocks including N-1 first valid data blocks and a first calibration data block, the error correction data packet comprises N error correction data blocks corresponding to the N initial data blocks in a one-to-one mode, a receiving end carries out a first calibration operation on the first valid data blocks according to the first calibration data block, if the first calibration result is correct, the first valid data blocks are processed, and otherwise, the receiving end conducts an error correction operation on the initial data packet according to the error correction data packet to obtain a correction data packet; the correction data packet comprises N-1 second valid data blocks and a second calibration data block, the receiving end carries out a second calibration operation on the second valid data blocks according to the second calibration data block, if the second calibration result is correct, the second valid data blocks are processed, and otherwise, the receiving end abandons the initial data packet and the error correction data packet and requests to resend the communication data packets.

Description

Technical field [0001] The invention relates to the field of communication, and 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 check and error correction of the current valid data block. The valid data block and the corresponding error correction data block Together they constitute a communication data block, and a series of communication data blocks together constitute a communication data packet. However, during the data transmission process of the above communication data packet, if an error correction data block has an error, 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. Resulting in communication failure. Summary of t...
