ABSTRACT:
A communication apparatus includes a transmission signal generation section1, a transmission signal control section2, a transmission section3, a leakage electric power detection section4, and an electric power control judgment section5.The transmission signal generation section1generates a transmission signal for carrying out transmission using a plurality of sub-carriers, under control of the transmission signal control section2, and has a transmission electric power control function with respect to each sub-carrier. The leakage electric power detection section4detects electric power which is leaked from a transmission line9among transmission electric power. The electric power control judgment section5judges necessity of transmission electric power control by the transmission signal control section2, on the basis of a leakage electric power signal from the leakage electric power detection section4, and in case that it was judged that transmission electric power control is necessary, it notifies that effect to the transmission signal control section2.The transmission signal control section2controls transmission electric power of a sub-carrier, on the basis of the leakage electric power signal from the leakage electric power detection section4.
