Communication apparatus, integrated circuit, and communication method
First Claim
1. A communication apparatus for transmitting a multi-carrier signal including a plurality of sub-carriers to another communication apparatus through a transmission channel, comprising:
- an integrated circuit;
a housing which accommodates the integrated circuit therein;
a first connector which is adapted for connecting a power line provided on a first side of the housing; and
an indicator which is provided on a second side of the housing;
wherein the integrated circuit includes;
a phase rotation section configured to rotate phase of at least one sub-carrier among the plurality of sub-carriers, by use of a first phase vector;
a multi-carrier signal output section configured to output first multi-carrier signal in which phase of at least one sub-carrier is rotated with the first phase vector;
a multi-carrier signal detection section capable of detecting a second multi-carrier signal, from another communication apparatus, in which phase of at least one sub-carrier is rotated with a second phase vector that differs from the first phase vector,a band setting section configured to set up at least one of a time band and a frequency band, on the basis of at least one of the first multi-carrier signal and the second multi-carrier signal; and
a communication section configured to perform communication with another communication apparatus through the transmission channel, by use of at least one of the time band and the frequency band, which are set up by the band setting section.

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.
