Abstract

Recently we have proposed the T-class of time-frequency distributions (TFD's) with time-only kernels to provide high-resolution and considerable cross-terms reduction for multicomponent FM signals. In this work we investigate the instantaneous frequency (IF) properties of two members of this class: the hyperbolic and the exponential T-distributions in the presence of noise. A comparison with two well-known TFD's, Wigner-Ville and Choi-Williams distributions, is also considered.
