Performance comparison. a Spectrogram of the signal v(t) in Eq. (25) embedded in AWGN at SNR level equal to 10 dB. b RSD. c Connected components detected by method \(\mathcal {M}\) with parameters K = 11 and Γ = 0.65. d Result given by the proposed method. e Plot of average MSE against SNR for signal v(t). The proposed method and the modified Viterbi-ADTFD method in [28] are compared
