To provide a multicarrier wired communication apparatus in which power efficiency can be enhanced by adjusting the electric energy of a signal being transmitted by each carrier depending on the delay time in the transmission line.
The multicarrier wired communication apparatus which transmits data from a master unit 100 to a slave unit 200 by using a plurality of carriers comprises a delay detection means 121 for detecting the delay time of a reception signal S4 received by a master unit side receiving circuit 120 for a transmission signal S1 transmitted from the master unit 100 to the slave unit 200, and an output determination means 30, for carrier selection and for each carrier, for adjusting the electric energy of a signal transmitted by each carrier according to the transmission distance calculated from the delay time detected by the delay detection means 121.
