Time-varying spectrum estimation of uniformly modulated processes by means of surrogate data and empirical mode decomposition

We propose a new estimate of the time-varying spectra of uniformly modulated processes. The estimate is based on a resampling scheme which incorporates empirical mode decompositions and surrogate data techniques. The performance of the method is studied via simulations.
