We emphasize the convergence analysis of the algorithm and study the convergent tendency of the quadrature error signal in each recursive step. The key to the proof is that the discrete Fourier transform value of the quadrature error signal is regarded as a vector, and the length/norm of the ...

In terms of the complexity, the proposed algorithm is better than the iterative Hilbert transform embedding (IHTE)33: \(O(N^2)\), which is one of the state-of-the-art methods for reconstructing the phase. Reconstruction performance of the proposed method Here, we examine whether the ...
