This paper presents an iterative instantaneous frequency estimation based on a cross localized Wigner-Ville distribution(X-LWVD). The convergence of this method is examined analytically and the performance in noise is compared with the peak detection of spectrogram and the peak detection of Wigner-Ville distribution (WVD) by computer simulation. It is demonstrated that this algorithm is an statistically effective method.
