Abstract
There are provided a frequency offset estimation method, a frequency offset estimation apparatus, an electronic device, and a computer-readable storage medium. The frequency offset estimation method includes: adopting a first frequency offset estimation method to perform frequency offset estimation on a demodulation reference signal (DMRS) sent from a terminal, to obtain a first frequency offset estimated value (); adopting a second frequency offset estimation method to perform frequency offset estimation on the DMRS sent from the terminal, to obtain a second frequency offset estimated value (); and determining a confidence factor according to the first frequency offset estimated value and the second frequency offset estimated value, and calibrating the second frequency offset estimated value according to the confidence factor to obtain a final frequency offset estimated value ().
