The invention discloses a high-speed refresh positioning
algorithm and
system based on
wireless signal processing, and relates to the technical field of high-speed refresh positioning, and the
algorithm specifically comprises the following steps: analyzing the cycle number of a
signal data unit in a current
refresh cycle, judging whether there is a
signal data unit with the cycle number not equal to the
current cycle number, and if yes, executing the following steps; when the signal data units exist and the number ratio of the signal data units exceeds a preset threshold value, a cross-cycle
data synchronization state judgment process is started; and on the basis of the time
label distribution, the historical data proportion and the source period number of the signal data units in the current refresh period, extracting feature information used for representing time consistency and a periodic structure, and inputting the feature information into a classification
discrimination function to determine a cross-period
data synchronization state corresponding to the current refresh period. According to the method, the problem of positioning mistaken refreshing caused by cross-cycle data
dislocation is solved, refreshing control based on synchronous state judgment is realized, and the positioning accuracy and the
system stability are effectively improved.
