<p>In order to minimize the size of internal data paths within a device with a series or pipelined architecture for calculating a Fourier transform of a predetermined initial size, a sequence of Fourier transform elementary processing operations of predetermined elementary sizes smaller than the initial size are performed on data blocks with successively reduced sizes from one elementary processing operation to the next. A global dynamic value (E1... E20) is determined for each data block derived from a current elementary processing operation (ET1), based on dynamic values of all of the data of the block. The block data are then reframed (DL2), taking into account the global dynamic value, before full subsequent elementary processing (ET2) on said data is carried out.</p> |
