Abstract:
1. A communication apparatus for executing a wired communication using a plurality of sub carriers, said apparatus comprising: a transmission signal generator for generating first and second transmission signals; a transmitter for transmitting the first transmission signal generated by the transmission signal generator; and a transmission signal controller for controlling a transmission power of the second transmission signal generated by the transmission signal generator based on a radiation power in a transmission line in correspondence with a frequency of the sub carrier of the first transmission signal generated by the transmission signal generator, wherein the transmitter transmits the second transmission signal the transmission power of which is controlled by the transmission signal controller via the transmission line, wherein the transmission signal controller reduces the transmission power of the sub carrier of the frequency in which the radiation power exceeds a predetermined value, and wherein the transmission signal controller intermittently changes the transmission power of the sub carrier of the frequency in which the radiation power exceeds the predetermined value.
