Title: Ofdm receiving device and ofdm receiving method
Inventor: SUGIMOTO MASAHIKO
IPC: H04J11/00
Filed: 2003-05-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide an OFDM receiving device for setting a time window of FFT in an optimum position even if a reception signal largely fluctuates with time and to provide a time window control method.  <P>SOLUTION: A selector 7 switches input to an FFT circuit 8 to output of a buffer memory 6 during an adjusting period of a time window setting position with respect to the FFT circuit 8 by a time window setting circuit 102. Thus, an OFDM signal of a base band, which is outputted from an orthogonal detector 15 and is stored in the buffer memory 6, is repetitively inputted to the FFT circuit 8 whenever the time window setting position is changed. Reception quality data having correlation with a change of the time window setting position is obtained from an S/N calculation circuit 94. Reception quality data are fed back to the time window setting circuit 102. Consequently, the time window of the FFT circuit 8 is set in a position from which satisfactory reception quality can be obtained.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
