Title: Receiving system and its method
Inventor: SUZUKI MITSUHIRO
IPC: H04J13/00
Filed: 2003-08-19
Abstract: <P>PROBLEM TO BE SOLVED: To estimate characteristics of a propagation path of time response effectively by carrying out inverse FET for distance measurement.  <P>SOLUTION: An OFDM method will be adopted probably in UWB standardization, and consequently an estimation value of a frequency region is obtained in a transmission path estimating unit. Since the distance measurement as a big feature of UWB requires the transmission path estimation value of time response, the conversion through the inverse FET should be carried out. Then, time response limitation is performed by using frequency region smoothing so as not to prepare a large additional FET for distance measurement. In this case, the time response can be obtained with a smaller number of FET points as compared with the conventional data receiving time.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
