Data synchronization method and device, signal receiving terminal and storage medium

The invention discloses a data synchronization method and device, a signal receiving terminal and a storage medium, and the data synchronization method comprises the steps: carrying out the logic operation of a received data signal and a predetermined local synchronization sequence symbol, obtaining a first logic operation result, carrying out the accumulation summation of the first logic operation result, and obtaining a second logic operation result; the method comprises the following steps: acquiring a first operation result, performing shift processing on a data signal to acquire a shift processing result, performing logical operation on the data signal and the shift processing result to acquire a second logical operation result, and performing accumulative summation on the second logical operation result to acquire a second operation result; and determining a ratio between the first operation result and the second operation result, determining a synchronization position according to the ratio and a prese
