Title:
SYNCHRONOUS FOLLOW-UP DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2004/040816
Kind Code:
A1
Abstract:
A replica generation section (103) multi-carrier-demodulates a known signal of a reception signal and generates a replica. A delay profile generation section (104) calculates a correlation value between the replica and the reception signal and generates a delay profile. An integrated value calculation section (105) integrates the correlation value for each predetermined range of the delay profile and obtains a plurality of integrated values. A maximum integrated value detection section (106) detects the maximum integrated value which is the greatest value among the integrated values. A demodulation timing detection section (107) detects a demodulation timing for performing multi-carrier demodulation from the position of the maximum integrated value.
