Summary:The invention discloses a signal processing method and device, equipment and a storage medium, and the method comprises the steps out of performing the inverse discrete Fourier transform (IDFT) of data in N channels at a current moment m by a transmitting terminal, and obtaining a transformation result; determining a displacement frequency K according to the channel number N and the up-sampling multiple L1; determining the current displacement according to the up-sampling multiple L1, the channel number N and the current moment m; during each displacement, performing cyclic left shift on the transformation result according to the current displacement to obtain a displacement result; using a filter subjected to multiphase decomposition and K-time interpolation for filtering in each channel;performing L1-time interpolation on the filtered result in each channel, and performing time delay addition on the data of each channel to obtain output data. Through multiple times of displacement,signal processing with a s
