Abstract: A communication apparatus repeatedly outputs a first multi-carrier signal SS during predetermined periods T1, T2, T3,..., and outputs a second multi-carrier signal RS whose phase vector is different from that of the first multi-carrier signal SS, at a predetermined timing based on the first multi-carrier signal SS. The communication apparatus further detects the second multi-carrier signal RS output from another communication apparatus, which uses a different communication method from the communication apparatus. Accordingly, both communication apparatuses can differentiate the first multi-carrier signal SS from the second multi-carrier signal RS without performing relatively cumbersome modulation and other processes.

Abstract: A transmitted digital signal from a digital signal processor is converted into an analog signal at an analog circuit, and then transmitted from transmission lines via a communication transformer. A communication apparatus has a plurality of communication modes that perform communication in different communication ranges. A controller in the digital signal processor changes an output level of the transmitted signal according to the communication modes. More specifically, the controller detects communication quality of the transmitted signal and lowers the output level of the transmitted signal within a range where the detected communication quality does not fall below predetermined quality.
