Title:
WIRELESS COMMUNICATION DEVICE AND CAPSULE-TYPE ENDOSCOPE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/225101
Kind Code:
A1
Abstract:
A wireless communication device 1 is provided with: a phase detection unit 61 that detects a signal change point at which a signal obtained by decoding a wireless signal having been received is changed and that detects, as a phase, a temporal position of the signal change point in one cycle defined by symbol rate setting; a vector generation unit 62 that generates a vector corresponding to the detected phase and having a predetermined magnitude; a vector synthesis unit 63 that generates a synthetic vector by synthesizing a plurality of the vectors generated; a calculation unit 64 that calculates a parameter having correspondence relationship with the magnitude of the generated synthetic vector; and a determination unit 65 that, on the basis of the calculated parameter, determines whether or not the wireless signal is a specific wireless signal.
