Figure 11From: Estimating the number of components of a multicomponent nonstationary signal using the short-term time-frequency Rényi entropy(a) SPWVD of a signal composed of an LFM component and two Gabor logons embedded in additive white noise with SNR = 10 dB; (b) number of components in time for the noise-free signal ( solid ), signal corrupted by additive white noise (SNR = 15 dB ( dashed ), and SNR = 10 dB ( dotted )).Back to article page
