<p><P>PROBLEM TO BE SOLVED: To provide a method and a device of UWB transmission/reception of a DPSK system. <P>SOLUTION: The UWB transmission device is embodied which includes a DPSK conversion unit for creating a bitstream by using a change in data stream, a UWB modulating unit for modulating each bit of the converted bitstreams into UWB pulse having different phases 0 and 1, and an RF module for transmitting the generated UWB pulse series to a radio channel. A UWB reception device is embodied which includes a time delay unit for delaying the RF module for receiving the UWB pulse series and the received UWB pulse series at a predetermined time, and a UWB demodulating unit for restoring the data stream through the time-delayed UWB signal and received UWB pulse series. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
