AI Technical Summary

⚠Technical Problem

In RFID communication, due to the large frequency offset accuracy and timing error of tags and readers, existing technologies are unable to track the frequency offset of the synchronization sequence in real time, resulting in irregular changes in the sampling points of the synchronization code sequence and inability to achieve accurate synchronization.

⚗Method used

By determining the sampling frequency of the current synchronization sequence, processing the sampling frequency based on a preset timing range, obtaining the soft value sequence of the current synchronization sequence, and adjusting the timing position when the preset target value is met, synchronization adjustment is achieved.

🎯Benefits of technology

It improves the timing accuracy of RFID synchronization, solves the problem of real-time tracking of synchronization sequence frequency deviation, and ensures the accuracy and efficiency of the synchronization process.

Abstract

Embodiments of the present disclosure relate to a method, device, equipment and medium for RFID synchronous search, wherein the method comprises: determining a sampling frequency of a current synchronization sequence; processing the sampling frequency based on a preset timing range to obtain a current soft value sequence of the current synchronization sequence, and determining a current timing position of the current synchronization sequence; and when the current soft value sequence meets a preset target value, synchronously adjusting the current timing position. By using the above technical solution, the problem that the frequency offset of the synchronization sequence cannot be tracked in real time is solved, the sampling frequency of the current synchronization sequence is determined, the sampling frequency is processed to complete fine timing of the current synchronization sequence and adjust the timing position of the synchronization sequence, and the timing accuracy of the synchronization is improved.
