Signal interference filtering method and related device

The embodiment of the invention discloses a signal interference filtering method and a related device. The device comprises a searching module, a correcting module and a filtering module. The searching module is used for carrying out parameter estimation in a selected area in the time-frequency domain to obtain estimation parameters, and the estimation parameter serve as an index for searching for compensation factors from a preset compensation factor lookup table, wherein the compensation factor lookup table comprises the various preset estimation parameters and the corresponding compensation factors. The correcting module is used for calculating an autocorrelation matrix corresponding to interference data in the selected area, and correcting the diagonal element of the autocorrelation matrix on the basis of the compensation factors. The filtering module is used for carrying out Cholesky decomposition on the corrected autocorrelation matrix to obtain a whitening matrix, and carrying out interference filtering on received signals in the selected area through the whitening matrix. By adopting the signal interference filtering method and the related device, interference on the signals in the selected area is effectively eliminated, the signal detection performance is improved, and operation is simple.
