Multi-carrier transmission system |
摘要 |
A first communication apparatus stores at least one frequency band influencing a reduction in transmission rate of a communication apparatus being present on an adjacent line adjacent to a communication line and including a range which is higher than an operation frequency band used by the communication apparatus in a storing unit. The first communication apparatus suppresses a transmission output of a signal in the frequency band stored in the storing unit to output a signal to the communication line.
