摘要

Embodiments of the present application provide a Doppler frequency offset estimation method and device based on a millimeter wave MIMO system. The method comprises: building a maximum likelihood estimation model for a Doppler frequency offset according to signals received by a receiving end in a millimeter wave MIMO system; determining a solution expression of the Doppler frequency offset according to the maximum likelihood estimation model; and estimating the Doppler frequency offset according to the solution expression. Compared with the prior art, by applying the embodiments of the present application, the Doppler frequency offset of the millimeter wave MIMO system can be estimated.
