Title:
OFDM信号受信装置及びOFDM信号受信方法
Document Type and Number:
Japanese Patent JP4623684
Kind Code:
B2
Abstract:
A Tu delay section ( 110 ) delays an analog-to-digital converted OFDM signal S01 by a time corresponding to an effective symbol period Tu. A correlation signal of an output of the Tu delay section ( 110 ) and OFDM signal S01 is obtained using a correlation calculating section ( 120 ). A delay section ( 130 ) outputs at least one delayed correlation signal obtained by delaying a correlation signal S02. Next, an adding section ( 140 ) performs addition of the correlation signal S02 and the delayed correlation signal, and then an interval integration section ( 150 ) performs transfer integration over a definite interval on a result of the addition. Then, a symbol period smoothing section ( 160 ) smoothes a result of the transfer integration for an interval of the effective symbol period of the OFDM signal S01, and then a window position detection section ( 170 ) calculates window position information from an output of the symbol period smoothing section ( 160 ).
