COMMUNICATION EQUIPMENT, COMMUNICATION SYSTEM, AND COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide communication equipment enabling efficient transmission according to a wire transmission line state, and the reduction of an effect of leakage power in a transmission line. SOLUTION: The communication equipment includes a transmission signal generator 1, a transmission signal controller 2, transmitter 3 and a leakage power detector 4. The transmission signal generator 1 generates a transmission signal for transmitting by use of a plurality of subcarrier by the control of the transmission signal controller 2, and has a transmission power control function on the basis of each subcarrier. The leakage power detector 4 detects transmission power leaking from a transmission line 9. The transmission signal controller 2 controls subcarrier transmission power based on a leakage power signal from the leakage power detector 4. COPYRIGHT: (C)2006,JPO&NCIPI
