Leak diagnosis of gas transport pipelines based on Hilbert-Huang transform

In this paper, an algorithm for gas pipeline leak detection based on Hilbert-Huang transform(HHT) studied. And both Fourier transform and HHT transform can be used to decompose pipeline leakage signals. The results that Fast Fourier Transform(FFT)…
