Abstract : We present in this paper an estimation method of the parameters of a generalized Gaussian noise. Under the hypothesis that a signal is sparse in the time-frequency domain, we use the kurtosis of the minimal values of the noisy signal, made of the unknown signal added to the noise to estimate.
