TIMING DETECTION METHOD, COMMUNICATION SYSTEM AND RECEIVING DEVICE

Title:

TIMING DETECTION METHOD, COMMUNICATION SYSTEM AND RECEIVING DEVICE

Document Type and Number:

WIPO Patent Application WO/2023/209864

Kind Code:

A1

Abstract:

A transmission device in the present invention intermittently transmits a physical frame of a transmission signal. A receiving device therein is equipped with a correlation calculation unit and a determination unit. The correlation calculation unit calculates the correlation between a received signal and a correlation sequence which has been subjected to doppler shifts of various types of shift amounts. The determination unit determines that a physical frame has been received when any of the calculation results from the correlation calculation unit exceeds a threshold.
