Abstract The cross polynomial Wigner-Ville distribution (X-PWVD) is applied to instantaneous frequency (IF) estimation of polynomial FM signals. The X-PWVD is used in a simple iterative algorithm, similar to the ,one recently proposed for the cross Wigner-Ville distribution (X-WVD) [2]. The advantage of the X-PWVD over the polynomial Wigner-Ville distribution [3] is that the former is linear with respect to the observed signal and as a result it attains the Cramer-Rao bound at lower signal-to-noise ratios (SNR's).
