Title:
DIGITAL AUDIO BROADCAST RECEIVER
Document Type and Number:
Japanese Patent JP3666162
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a digital audio broadcast receiver by which a phase error signal with less effect of leakage from other carrier due to frequency deviation is obtained.
SOLUTION: A phase error detector 12b detects a phase error from data of a differential demodulator 11, a mean value processing section 21 finds a mean value of phase errors, a memory 19 stores the phase error of each carrier of an output of the phase error detector 12b, a phase error correction section 23a excludes phase errors whose sign is inverse to that of the mean value among the phase errors stored in the memory 19 and obtains again the mean value of the phase errors to obtain the phase error signal with less effect of leakage from other carriers.
