Elimination of interference component in Wigner-Ville distribution for the signal with 1/f spectral characteristic
A new technique for interference-term suppression in the Wigner-Ville distribution (WVD) is proposed for signals with a 1/f spectrum shape. The spectral characteristic of the signal is altered by f/sup /spl alpha// filtering before time-frequency analysis and compensated after analysis. With the uti...

| description | A new technique for interference-term suppression in the Wigner-Ville distribution (WVD) is proposed for signals with a 1/f spectrum shape. The spectral characteristic of the signal is altered by f/sup /spl alpha// filtering before time-frequency analysis and compensated after analysis. With the utilization of the proposed technique in a smoothed pseudo Wigner-Ville distribution, an excellent suppression of the interference component can be achieved. The authors apply this technique to the heart rate variability signal. |
