Transmission/reception method and device for isolated communication

A transmission/reception method for isolated communication, the method comprising:

• performing transmission, wherein bit streams are extracted from data and two or more predetermined number of bits are modulated into one DC balanced symbol so as to generate a signal in which a plurality of symbols are listed, thereby transmitting the signal through an isolated communication circuit;
• and
• performing reception, wherein the signal is received through the isolated communication circuit and the plurality of symbols included in the signal are demodulated into the two or more predetermined number of bits so as to generate the bit streams and organize the bit streams into the data, wherein each symbol modulates two bits of the data by using two types of pulses,
• wherein each symbol comprises two pulses of any one type among the two types of pulses when the two bits of the data are the same as each other and comprises one pulse of any one type among the two types of pulses when the two bits of the data are different from each other, or
• each symbol comprises one pulse of any one type among the two types of pulses when the two bits of the data are the same as each other and comprises two pulses of any one type among the two types of pulses when the two bits of the data are different from each other.

A transmission/reception device for isolated communication, the device comprising:

• a transmission device configured to extract bit streams from data and modulate two or more predetermined number of bits into one DC balanced symbol so as to generate a signal in which a plurality of symbols are listed and transmit the signal through an isolated communication circuit;
• and
• a reception device configured to receive the signal through the isolated communication circuit and demodulate the plurality of symbols included in the signal into the two or more predetermined number of bits so as to generate the bit streams and organize the bit streams into the data,
• wherein each symbol comprises:
• a pulse;
• and
• a space having no pulse until a next symbol after the pulse.
