  • MULTIPLE ACCESS COMMUNICATION SYSTEM AND PHOTOVOLTAIC POWER GENERATION SYSTEM
    Publication number: 20140341235
    Abstract: Each transmitter (4) included in a first transmitter group (40A) transmits, on a first electric wire (2A), a current signal representing a change in current in accordance with a transmission bit sequence. Each transmitter (4) included in a second transmitter group (40B) transmits, on a second electric wire (2B) that is connected in parallel with the first electric wire, a current signal representing a change in current in accordance with a transmission bit sequence. A current detection unit (6A) outputs an electric signal representing a change in a difference current between a first current (IA) flowing through the first electric wire (2A) and a second current (IB) flowing through the second electric wire (2B). A receiver (5A) identifies and receives a reception bit sequence corresponding to the transmission bit sequence of each transmitter (4) included in the first and second transmitter groups, by processing the first electric signal.
