Document Type and Number:
Japanese Patent JP3891373
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To further reduce the power consumption of a demodulator in comparison to that of a conventional demodulator, without deteriorating the reception quality.
SOLUTION: This demodulator is provided with a delay profile measurement means 41 that measures a delay profile of a base band signal, while changing a measurement time to measure a delay profile S41 of the base band signal S6 to minimize the measurement time and avoiding deterioration in reception power level to thereby further reduce power consumption in comparison to conventional demodulators, without deteriorating the reception quality.
