Time-Frequency mapping for synthesized signals, S 1 (t) and S 2 (t) , Δf=0.5 Hz. (a1) and (b1) are the synthetic signal S1(t) and S2(t) respectively; (a2) and (b2) are the time-frequency mappings obtained with BMFLC-KF; (a3) and (b3) are the time-frequency mappings obtained with BMFLC-KS; (a4) and (b4) are the time-frequency mappings obtained with BMFLC-LMS; (a5) and (b5) are the time-frequency mappings obtained with STFT; (a6) and (b6) are the time-frequency mappings obtained with CWT.
