Document Type and Number:
WIPO Patent Application WO/2021/161736
Kind Code:
A1
Abstract:
Provided is a receiver that can accurately derive an I/Q signal phase difference. The receiver includes: a segment detection unit that, on the basis of a leading edge segment or a trailing edge segment of a phase expressed by I/Q signals generated on the basis of an advertise packet transmitted from a transmitter, detects a segment between the leading edge and the trailing edge of the phase; and a segment setting unit that extracts, from among segments between the leading edge and the trailing edge, a segment in which a first fluctuation amount of the phase is not greater than a first prescribed amount, and sets the extracted segment to be the segment for detecting the I/Q signal phase.
