Error correction method and error correction apparatus

An error correction apparatus, comprising:

• an obtaining circuit, configured to obtain a decision signal of a decision feedback equalizer (DFE), and further configured to obtain at least one of an input signal, an equalized output signal, or a difference of the DFE, wherein the difference is a difference between a level value of the decision signal and a level value of the equalized output signal;
• a detection circuit, configured to determine a symbol location of an end of burst error of the decision signal based on detection of at least one of the decision signal, the equalized output signal, or the difference;
• and
• an error correction circuit, configured to:
• in response to the detection circuit detecting the symbol location, perform error correction on the decision signal based on the at least one of the input signal, the equalized output signal, or the difference.

A non-transitory computer readable storage medium, comprising an instruction, which when executed by a computer, causes the computer to perform an error correction method including the following operations:

• obtaining a decision signal of a decision feedback equalizer (DFE);
• obtaining at least one of an input signal, an equalized output signal, or a difference of the DFE, wherein the difference is a difference between a level value of the decision signal and a level value of the equalized output signal;
• determining a symbol location of an end of a burst error of the decision signal based on detection of at least one of the decision signal, the equalized output signal, or the difference;
• and
• in response to the symbol location being determined, performing error correction on the decision signal based on the at least one of the input signal, the equalized output signal, or the difference.
