Data communication method and apparatus using forward error correction

摘要

A data communication method using forward error correction (FEC) includes: receiving at least one of symbols that constitute one encoding block unit; extracting information related to parameters that adjust an FEC encoding rate from the at least one symbol; determining whether an error may be corrected based on the extracted information related to the parameters and a number of symbols with errors from among the symbols that constitute the encoding block unit; and transmitting feedback information related to the symbols prior to the symbols that constitute the encoding block unit being completely received based on the determination of whether an error may be corrected.
