Use of the cross Wigner-Ville distribution for estimation of instantaneous frequency
B. Boashash, Peter O’Shea · IEEE Transactions on Signal Processing · 1993
An iterative instantaneous frequency (IF) estimation scheme is presented in which successive IF estimates are obtained from the peak of the cross Wigner-Ville distribution (XWVD), using a reference signal synthesized from an initial IF estimate. Theoretical and practical aspects of performance are discussed, and the performance is compared with that of other methods.>
