Document Type and Number:
Japanese Patent JP2842820
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent hindrance of control by allowing the receiver to trace fluctuation even when the fluctuation in fading is irregular and high. SOLUTION: A reception means 3 extracts a radio wave including an object signal from a received radio wave and provides an output of an analog signal. An A/D converter means 4 samples an analog signal and converts it into a digital signal. A fluctuation section 52 receives the digital signal and stores it when a power level is at a peak, it is stored and a difference between a mean power level and a power level is detected from recent N-sets of peaks stored precedingly from now. An amplification factor calculation section 53 decreases a power level difference from a maximum value of the received power level and it is divided by the mean power level to obtain an amplification factor. A signal amplifier section 54 amplifies the digital signal received this time at the amplification factor and provides an output. A demodulation means 6 receives the digital signal to provide an output of a control signal controlling a radio receiver 1.
