Abstract :
This paper introduces a new time-frequency representation called the bicorspectral transform (BET), derives most of its theoretical properties and details relevant applications. This representation is devoted to non-Gaussian processes either stationary or not that exhibit non-vanishing third order moments. It is also closely related to the deterministic correlation between the signal and its Wigner-Ville distribution which yields efficient implementation with almost the same numerical complexity as a pseudo-Wigner-Ville representation
