Abstract

The invention relates to the field of communication data error correction, in particular to a system and method for error correction of communication data. The system includes: a state sampling module, a correction module, a decoding module and a verification module. By increasing the oversampling of the serial signal, the noise bit stream is output, and compared with the error bit stream output by the verification module, so as to accurately locate the wrong data bit in the information bit stream and correct it, so as to realize the maximum communication of a single bit stream Limit data correction to avoid data loss or communication retransmission, thereby improving data communication efficiency and improving servo control performance. It can effectively solve the problem of inaccurate data in the control cycle caused by data communication errors under the premise that the control cycle can only carry out one data communication, and correct the information bit stream according to the information of the noise bit stream and the error bit stream to the maximum extent. Recover the correct data and improve control reliability.

Description

technical field [0001] The invention relates to the field of error correction of communication data, in particular to a system and method for error correction of communication data. Background technique [0002] In the field of wired communication, in order to save costs and improve reliability, data exchange between devices is generally carried out by means of serial communication. The data sending device maps a data with Q bits to the serial signal one by one according to the sending edge of the communication clock agreed between the devices; the data receiving device also maps the Q bits to the serial signal according to the receiving edge of the agreed communication clock , the Q bits of data on the serial signal are received one by one and combined into Q bits of data. [0003] In this communication process, with the extension of the communication line between devices and the complexity of the electromagnetic environment around the line, it is easy to interfere with th...
