Patent ID: 8897396

Claim:
A pulse receiver for receiving a burst signal containing information to transfer and decoding and outputting the information, comprising: a comparator provided for comparing the burst signal with a reference voltage and outputting a pulse train corresponding to the burst signal; a decode unit provided for receiving the pulse train from the comparator, decoding the pulse train to predetermined basic data sequentially and outputting the data as the information, and counting, for a predetermined count time, a decoding success rate which is a number of times of decoding of the pulse train to the basic data; and a control unit provided for receiving the decoding success rate from the decode unit, calculating a deviation by subtracting the decoding success rate from a predetermined decoding target rate, when the deviation is greater than a predetermined first determination value that is equal to or greater than 0, renewing a set value of the reference voltage so as to reduce the deviation and outputting the set value to the comparator, and repeating renewal of the set value of the reference voltage until the deviation becomes equal to or less than the first determination value, wherein, when the deviation is greater than the first determination value, the control unit renews the set value by adding, to the set value, a proportional component obtained by multiplying the deviation by a predetermined proportional control constant and an integral component obtained by multiplying a cumulative value of the deviation by a predetermined integral control constant, and when the deviation is equal to or less than the first determination value and the cumulative value of the deviation is greater than a predetermined second determination value that is equal to or greater than 0, the control unit subtracts an offset value corresponding to an offset voltage from the set value and resets the cumulative value of the deviation to 0.
