The high-order ambiguity function (HAF) was introduced for the estimation of polynomial-phase signals (PPS). Currently the HAF suffers from noise-masking effects and from the appearance of undesiredâ€¦ (More)

A time-frequency classifier is applied for human gait classification. Time-frequency (t-f) quadratic distributions are used for time-frequency signal representations. Three specific motions areâ€¦ (More)

The high-order ambiguity function (HAF) was introduced for the estimation of polynomial-phase signals (PPS) embedded in noise. Since the HAF is a nonlinear operator, it suffers from noise-maskingâ€¦ (More)

We investigate a characterization of underwater acoustic signals using extracted time-scale features of the propagation channel model for medium-to-high frequency range. The underwater environmentâ€¦ (More)
