PROBLEM TO BE SOLVED: To provide a method of error correction using a repetition transmission scheme by which an error-correction capability is improved and high-speed data transfer is enabled. SOLUTION: The method of error correction is applied to communication between two communication devices at least one of which is mounted to a mobile. Information transmitted repetitively is held while being sorted into reception information groups in accordance with a communication device ID and a sequence number, error detection is performed repetitively in the order of reception and if any error is detected, majority determination is performed on the basis of a plurality of pieces of error detected reception information. Reception information is then generated on the basis of the majority determination, error detection is performed and if there is no error, a packet reception success is determined. If there is any error, error detection is further performed for the next received reception information in the reception information group. When performing the majority determination for even-numbered reception information, a plurality of pieces of reception information are generated by replacing unfixed bits upon which the majority determination is disabled with a logic pattern determined by the number of unfixed bits, and error correction is performed by applying error determination to a plurality of generated reception signals.
