This new approach consists of sifting an ensemble of white noise-added signal (data) and treats the mean as the final true result. Finite, not infinitesimal, amplitude white noise is necessary to force the ensemble to exhaust all possible solutions in the sifting process, thus making the different scale signals to collate in the proper intrinsic mode functions (IMF) dictated by the dyadic filter banks. As EEMD is a time\u2013space analysis method, the added white noise is averaged out with sufficient number of trials; the only persistent part that survives the averaging process is the component of the signal (original data), which is then treated as the true and more physical meaningful answer. The effect of the added white noise is to provide a uniform reference frame in the time\u2013frequency space; therefore, the added noise collates the portion of the signal of comparable scale in one IMF. With this ensemble mean, one can separate scales naturally without any a priori subjective criterion selection as in the intermittence test for the original EMD algorithm. This new approach utilizes the full advantage of the statistical characteristics of white noise to perturb the signal in its true solution neighborhood, and to cancel itself out after serving its purpose; therefore, it represents a substantial improvement over the original EMD and is a truly noise-assisted data analysis (NADA) method.<\/jats:p>","DOI":"10.1142\/s1793536909000047","type":"journal-article","created":{"date-parts":[[2008,10,17]],"date-time":"2008-10-17T03:06:49Z","timestamp":1224212809000},"page":"1-41","source":"Crossref","is-referenced-by-count":7484,"title":["ENSEMBLE EMPIRICAL MODE DECOMPOSITION: A NOISE-ASSISTED DATA ANALYSIS METHOD"],"prefix":"10.1142","volume":"01","author":[{"given":"ZHAOHUA","family":"WU","sequence":"first","affiliation":[{"name":"Center for Ocean\u2013Land\u2013Atmosphere Studies, 4041 Powder Mill Road, Suite 302, Calverton, MD 20705, USA"}]},{"given":"NORDEN E.","family":"HUANG","sequence":"additional","affiliation":[{"name":"Research Center for Adaptive Data Analysis, National Central University, 300 Jhongda Road, Chungli, Taiwan 32001, Taiwan"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1098\/rspa.1998.0193"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.fluid.31.1.417"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1142\/5862"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1201\/9781420027532"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1109\/LSP.2003.821662"},{"key":"rf6","doi-asserted-by":"publisher","DOI":"10.1098\/rspa.2003.1221"},{"key":"rf7","unstructured":"P.\u00a0Flandrin, P.\u00a0Gon\u00e7alv\u00e8s and G.\u00a0Rilling, Hilbert\u2013Huang Transform: Introduction and Applications, eds.
