<p><P>PROBLEM TO BE SOLVED: To provide a method, a device and a system for determining a signal arrival direction. <P>SOLUTION: The first and second UWB waveforms of a signal are received by one or more of antenna of a UWB transceiver to determine the signal arrival direction (S102). A window defined by a head portion of the signal is defined by the first and second UWB waveforms. The first and second amplitude values are calculated respectively as to the first and second UWB waveforms in the window. An amplitude ratio is calculated as to the first and second amplitude values, and is compared with a calibration data to determine the signal arrival direction (S110). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
