The main tool is the holomorphic functional calculus developed by McIntosh in 1980s. This is a joint work with Yanping Chen, Xuan Thinh Duong, Ji Li and Wenyu Tao.

WebReferring to the wavelet construction method of Littlewood–Paley and Meyer, the empirical wavelet function is constructed. After Λ n is determined, the empirical wavelet is used as a bandpass filter. The formulas of the empirical wavelet function ψ ∧ n (ω) and the empirical scale function ϕ ∧ n (ω) are as follows :
