Title:
SYNCHRONIZATION DETECTION DEVICE, SYNCHRONIZATION DETECTION METHOD, AND SYNCHRONIZATION DETECTION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/004454
Kind Code:
A1
Abstract:
Provided are a synchronization detection device, a synchronization detection method, and a synchronization detection program which make it possible to follow, in a short time, a frequency deviation of an intermediate frequency (IF) after a radio frequency is down-converted. The synchronization detection device (11) comprises: a band limitation unit (111) in which a plurality of filters (111a-111e), of which the central frequencies are different, limit the bands of reception signals with respect to the reception signals received from the outside and output a plurality of band limited signals; a detection and demodulation unit (112) which detects and demodulates each of the plurality of band limited signals and outputs a plurality of detection signals; a synchronization detection unit (113) which synchronously detects each of the plurality of detection signals and outputs a plurality of correlation values; and a synchronization evaluation unit (114) which selects a prescribed filter (111p) from among the plurality of filters (111a-111e) on the basis of the plurality of correlation values.
