Consider observations where random signals are randomly present or absent in independent and additive white Gaussian noise (AWGN). By using a recently established limit theorem, we introduce a new estimator for the estimation of the noise standard de

International audience; Given some signal additively corrupted by independent white Gaussian noise with unknown standard deviation σ,we present a new estimator ofσ. This estimator derives from a theoretical result presented and commented in the pap
