Noise Analysis of the Cross Wigner-Ville Distribution Based Instantaneous Frequency Estimation Method
Noise analysis of the Cross Wigner-Ville distribution (XWVD) based method for the signal components instantaneous frequency (IF) estimation is presented. The utilized method deliberately forms cross-terms in the XWVD between the analyzed signal and a reference signal, and it yields a scaled and time shifted image that closely resembles the IFs of the signal components. Based on the geometrical rules that govern interferences, and by using a reference signal that is well localized in time and frequency, the time-frequency coordinates of the components IF are calculated in an automatic way. The effect of noise on the method's performance is tested for various levels of additive white Gaussian noise. Statistical performance measures are given for multi-component synthetic signals examples.
