Error correction device, error correction method, and communication device

An error correction method used in a communication device transmitting data of a predetermined transmission rate through a plurality of transmission lines configured in one carrier or one channel band, comprising:

• correcting errors of the data transmitted through the plurality of transmission lines by a plurality of error correction circuits;
• and
• combining the plurality of transmission lines to the plurality of error correction circuits by a combining portion,
• wherein the plurality of transmission lines includes a first transmission line, and a second transmission line having a lower transmission characteristic than the first transmission line,
• the plurality of error correction circuits includes a first error correction circuit, and a second error correction circuit having lower error correction capability and power consumption than the first error correction circuit, and
• by using a function of the combining portion of combining a plurality of error correction circuits in one transmission line to allocate data of the transmission line, the combining portion, the first transmission line is combined with the second error correction circuit at a higher rate than the first error correction circuit and the second transmission line is combined with the first error correction circuit at a higher rate than the second error correction circuit.
