TRANSMISSION OUTPUT CONTROLLER, MULTI-CARRIER TRANSMISSION SYSTEM, TRANSMISSION POWER CONTROL METHOD AND TRANSMISSION OUTPUT CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a multi-carrier transmission system which prevents generation of noise in a high frequency band higher than an operation frequency band used by a communication apparatus, and avoids reduction in transmission rate of the communication apparatus. SOLUTION: A first communication apparatus (100) stores at least one frequency band influencing a reduction in transmission rate of a communication apparatus (500)present on an adjacent line (400) adjacent to a communication line (300) and including the high frequency band which is higher than the operation frequency band used by the communication apparatus (500) in a storing unit (104). Then, the first communication apparatus (100) suppresses a transmission output of a signal in the frequency band stored in the storing unit to output a signal to the communication line.
