Abstract
A device for processing digital data. A module (M, M) produces on a data vector of the frequency domain Z(k), wherein K varies from 0 to N−1, a convolution with a function U, convolution which corresponds to a cancellation in the time domain of the samples of the inverse transform of Z(k). The function U is in the form: U(k)=sin c(k−k/2.e)−jπ(α(k−k/2.P(k)), wherein Kis a constant integer and P(k) a weighting window symmetrical about k.
