Communication method, device, equipment, system and readable storage medium

The invention provides a communication method, device, equipment, system and a readable storage medium, and relates to the field of communication. The method comprises the following steps: after acquiring a first frequency signal and a second frequency signal with the same clock signal, respectively performing frequency offset estimation on the first frequency signal and the second frequency signal to obtain a first frequency offset estimation value and a second frequency offset estimation value, and correcting the second frequency offset estimation value according to the first frequency offset estimation value, the first frequency offset estimation value and the second frequency offset estimation value are synthesized for calculation to obtain a frequency offset estimation result. Thus, the frequency offset estimation value of the second frequency signal with relatively low accuracy can be corrected by using the first frequency offset estimation value with relatively high accuracy, and the error of the frequency offset estimation result of the second frequency signal is reduced, so that the frequency offset correction performance of the second frequency signal can be ensured in subsequent steps such as correction, and the accuracy of correction is improved. The communication stability of the communication system is improved.
