The application discloses a downlink data anti-interference processing method for a 5G terminal, characterized in that at least comprising the following steps: in the 5G terminal, a multi-antenna is used to receive a downlink PDSCH signal, and FFT processing is performed on each time slot signal of each antenna to obtain a frequency domain multi-path signal; a plurality of subbands are divided in the frequency domain, and each subband signal is spliced in rows according to time slots to form a first matrix; the first matrix is subjected to centralization and whitening preprocessing to obtain a second matrix; in step S13, the second matrix is subjected to initial spatial domain weighting and merging, a complex FastICA algorithm is used to iteratively solve the optimal value of the spatial domain weighting coefficient, and the spatial domain weighting and merging of the second matrix is performed by using the final solution of the iteration to obtain a final anti-interference output signal. The application further discloses a corresponding storage medium and device. By implementing the application, the calculation amount can be reduced, the convergence speed is improved, and the anti-interference effect is very good for both weak interference and strong interference.
