Title: Digital broadcast receiver
Inventor: YOSHINAGA MASAYUKI
IPC: H04N7/04
Filed: 2000-03-22
Abstract: PROBLEM TO BE SOLVED: To provide a digital broadcast receiver that can normally demodulate a received signal. SOLUTION: The digital broadcast receiver 10 includes a 2nd AFC circuit and an input terminal S6 provided to the 2nd AFC circuit receives a pilot signal ERPI extracted from I' and Q' signals subjected to FFT processing. Delay circuits 50a-50d delay the pilot signal ERPI by one point each among -2 to 1 point with respect to a referenced pilot signal PI. The correlation between the delayed pilot signal ERPI and the pilot signal is detected and a carrier position selection circuit 56 selects a head carrier position of data on the basis of the result of correlation. When two head carrier positions or more exist, the carrier position selection circuit 66 selects one head carrier position coincident with the head carrier position of data included in a preceding symbol stored in a 2nd memory 60. Thus, the frequency error can be corrected on the basis of the accurate head carrier position.
