ABSTRACT: Hilbert Huang Transform (HHT) and Local Mean Decomposition (LMD) are two adaptive
signal processing methods. Firstly, the principle of two kinds of methods was presented. And then taking the
simulated signal as example, the comparative study was carried on through the decomposition and reconstruc-
tion, instantaneous amplitude and frequency ...
