Also known as Iterated Hilbert Transform transform, is a novel transform that allows an asymptotically exact representation of non-stationary signals. This transform has higher performance than empirical mode decomposition, also known as Hilbert-Huang transform, periodic algebraic separation and energy demodulation (PASED), and multiband energy separation algorithm (MESA).
