The invention discloses a frequency offset estimation method and device. The method comprises: determining a strong path for each user, and reconstructs the training sequence matrix G 'and the channel impulse response vector H' according to the path determined; were grouped according to the training sequence of the total number of signal receiving path, corresponding to each training sequence, using G 'structure of each signal the corresponding matrix G: I', and construct the noise signal corresponding to the each column vector of N down I; using the G: I ', constructed H' and N down I, get the equations corresponding to each training sequence signal, solving the equations, N yuan vector H: I '; according to the H: I' calculated each path frequency offset.
