METHOD AND APPARATUS FOR POWER LINE COMMUNICATION |
摘要 |
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. |
