Frequency offset estimation method and device and storage medium

The invention relates to the technical field of communication, in particular to a frequency offset estimation method and device and a storage medium. The method comprises the following steps: acquiring a local PBCH signal, wherein the local PBCH signal comprises local PBCH signals respectively corresponding to a plurality of estimated samples obtained by reconstruction; obtaining a frequency domain receiving PBCH signal, wherein the frequency domain receiving PBCH signal comprises received frequency domain receiving PBCH signals corresponding to the plurality of estimation samples; and performing frequency offset estimation according to the local PBCH signal and the frequency domain receiving PBCH signal to obtain a frequency offset estimation result. According to the embodiment of the invention, the local PBCH signal and the frequency domain received PBCH signal are used as the statistical samples of PBCH frequency offset estimation, the coverage range of the scheme is increased in amode of increasing the nu
