摘要： PROBLEM TO BE SOLVED: To allow for sharing of the same resources among a plurality of multiple access systems using a plurality of wires connected in parallel for signal transmission.SOLUTION: Each transmitter (4) included in first and second transmitter groups connected with first and second wires (2A and 2B) connected in parallel operates to transmit a current signal, indicating current change based on a transmission bit string, to any one of the first or second wire (2A or 2B). A current detection unit (6A) operates to output a first electric signal indicating the change in the difference current of a first current (IA) flowing through the first wire (2A) and a second current (IB) flowing through the second wire (2B). A receiver (5A) operates to receive the first electric signal while processing to identify the reception bit string corresponding to the transmission bit string of each transmitter (4) included in the first and second transmitter groups.
