An efficient procedure for obtaining time–frequency representations under high influence of impulsive noise is proposed in this paper. The procedure uses the fast Fourier transform based algorithm instead of sorting procedures common in the case of various robust time–frequency representations proposed recently. Concentration measure is used to select a free parameter of the transform.
