    摘要： Apparatus and method of transmitting a preamble having additional information in differential modulation packet data communication. The apparatus includes a phase rotator that outputs a phase rotation quantity corresponding to additional information to be applied to a transmission target packet, a transmission-multiplier that multiplies the phase rotation quantity output from the phase rotator by a preamble to be transmitted, a symbol mapper that converts header and payload data to be applied to the transmission target packet into symbols and outputs the same, a multiplexer that processes an output signal of the transmission-multiplier and an output signal of the symbol mapper to be selectively output through an output end to form a symbol stream in units of packets, and a differential symbol converter that converts the symbol stream output from the multiplexer according to a predetermined differential modulation method and outputs the converted symbol stream.
