Abstract:
A communication apparatus which performs a carrier detection and is connected to a transmission line includes: a carrier detecting means for detecting a first control signal for the carrier detection and a second control signal for the carrier detection; a comparing means for comparing carrier detecting results obtained by the carrier detecting means; and a control means for controlling at least one of a symbol length of the first control signal and a symbol length of the second control signal based upon a comparison result obtained by the comparing means.
