Title: Ofdm frequency deviation detection apparatus and correction apparatus thereof
Inventor: TANAKA TADAAKI
IPC: H04J11/00
Filed: 2006-02-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide an apparatus for detecting and correcting the frequency change (frequency deviation) that occurs, when receiving an OFDM signal in a traveling object, such as an automobile.  <P>SOLUTION: An OFDM signal, to which a guard interval is added, is the same signal as a partial signal (signal A) close to the head of a symbol and a partial signal (signal B) being within the same symbol term as the signal A and being separated for one valid symbol term. If there is frequency deviation in the OFDM signal, however, the two signals become different, since a phase difference is incurred between the signals A and B in proportion to the amount of the frequency deviation. The present invention is adapted to detect the phase difference and to correct the frequency deviation of the OFDM signal.  <P>COPYRIGHT: (C)2007,JPO&INPIT
