Abstract
A data communication system includes a terminal identification information adding unit generating a unit carrier wave including a predetermined plurality of periods of carrier waves and arranging the unit carrier wave in arrangement patterns differing at every transmission terminal to generate a unit carrier row signal shorter than one bit of the digital transmission data, a transmission timing determination unit detecting a binary inversion timing of the digital transmission data and causing the terminal identification information adding unit to transmit the unit carrier row signal every time the binary is inverted, a reception timing distinguishing unit generating a reception timing signal in synchronization with reception of the unit carrier row signal and collecting the reception timing signal of the unit carrier row signal of the same type, and a digital data restoring unit inverting the binary according to the collected reception timing signal, restoring the digital transmission data.
