Document Type and Number:
WIPO Patent Application WO/2021/039560
Kind Code:
A1
Abstract:
This reception device (1) has: a measurement unit (150) that measures, on the basis of a differential signal obtained by amplifying a noise-based signal, a first number of times by which a first phase and a first opposite phase that is an opposite phase of the first phase intersect each other; an oscillator (160) that oscillates a first signal; a comparison unit (170) that compares the first number of times with a preset first reference value; and a signal output unit (180) that outputs a second signal indicating that an optical signal is received when the first number of times coincides with the first reference value. When receiving the first signal, the measurement unit (150) resets the first number of times.
