Embodiments of the present application provide a clustering-based frequency deviation determination and elimination method and device, and an electronic apparatus. The clustering-based frequency deviation determination method comprises: determining a constellation diagram of a received signal; determining N different values in a preset frequency interval, and using the determined N different values as N frequency deviation estimated values; with respect to each frequency deviation estimated value, correcting the constellation diagram according to the frequency deviation estimated value, so as to acquire a corrected constellation diagram, performing clustering on signal points in the corrected constellation diagram, and calculating the areas of clustered signal regions in the constellation diagram; and determining a frequency deviation estimated value corresponding to a signal region having the smallest area to be a frequency deviation value. Embodiments of the present application improves the stability of calculation of a frequency deviation value.
