Embodiments of the present invention provide a method, device, and system for frequency offset estimation and channel estimation, which relate to the field of wireless communications technologies and improve accuracy of frequency offset estimation and channel estimation in a distributed microwave MIMO system. A method for frequency offset estimation and channel estimation comprises: when an interference signal in received data is not obtained, performing frequency offset estimation on the received data to obtain a frequency offset estimation result; after obtaining the interference signal in the received data, performing frequency offset estimation on the received data according to the interference signal to obtain a frequency offset estimation result; performing channel estimation on the received data according to the frequency offset estimation result to obtain a channel estimation result; and obtaining the interference signal according to the frequency offset estimation result and the channel estimation result, the interference signal being used as a parameter of the frequency offset estimation. |
