Corrections concern the results given in Section 4 of the above paper for the local polynomial Wigner-Ville estimator. These corrections refine the assumption about the correlation function of the continuous time observation noise and Eq. (38) for the covariance matrix of the local polynomial WVD estimator. We wish to emphasize that the produced corrections… (More)
