Abstract

The invention discloses a processing method for a target spectrum matrix. According to the method, for each data frame, a normalized window function sub-sequence corresponding to the data frame is obtained through the corresponding data frame information according to the obtained target data frame information corresponding to a target frequency spectrum matrix; and the normalized signal sequence corresponding to the data frame can be directly obtained through the normalized window function sub-sequence without additional normalization operation, so that the calculation amount for processing atarget spectrum matrix is greatly reduced; and the operation speed and the operation efficiency of the terminal equipment during short-time inverse Fourier transform operation are improved.
