<P>PROBLEM TO BE SOLVED: To provide a power line communication apparatus, integrated circuit, and power line communication method in which communication can be performed while avoiding a signal collision. <P>SOLUTION: A power line 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, in a predetermined timing based on the first multi-carrier signal SS. The power line communication apparatus further detects the second multi-carrier signal RS outputted from another communication apparatus, which uses a different communication method from the communication apparatus. Accordingly, both power line communication apparatuses can identify the first multi-carrier signal SS from the second multi-carrier signal RS without performing relatively high load modulation processing or the like. <P>COPYRIGHT: (C)2007,JPO&INPIT |
