Abstract
This invention relates to spreading code producing apparatus, which comprises: two phase shifters for spreading code which receive bits for determining spreading codes and phase information and producing spreading codes; and multiplexers which receive two spreading codes produced said two phase shifters for spreading code, receive bits through separate way which defines outputting order of the received two spreading codes and produce spreading codes with same length as said received two spreading codes. Therefore, many information using few spreading codes can be transmitted so that data transmission rate can be raised. Furthermore, communication service with high speed can be performed among communication devices using human body communication etc.
