Results show the proposed algorithm provides no spurious IMF for these functions and is not placed in an infinite loop. EMD types comparison on ECG(Electrocardiography) signals reveal the improved EMD was an appropriate algorithm to be used for analyzing biological signals. WebMar 15, 2013 · Based on empirical mode decomposition (EMD) and Hilbert spectral analysis (the two together are usually called the Hilbert–Huang transform (HHT)), Huang et al. [9] established the relationship between the Hurst exponent and Hilbert transform by studying the amplitude–frequency distribution and taking the structure function as a bridge.
