Signal Processing applied to Networks
Time-Frequency Analysis
Time-Scale Analysis
Description: Wigner distribution is adaptatively smoothed by mean of a signal-dependent diffusion scheme. The corresponding partial differential equations are designed so as to satisfy time-frequency or time-scale shifts invariance. In both cases they smooth interference terms and noise while preserving the good concentration of signal terms.
