This method succeeds in harmonic retrieval in colored non Gaussian noise, especially when the noise is symmetrically distributed or there exist quadratic phase coupled cosinusoids.
An improved Hilbert vibration decomposition (HVD) method was introduced to the non-integer harmonic analysis in electrical power system.
针对现有电力系统非整数次谐波分析法的不足,提出了一种改进的希尔伯特振动分解(HVD)方法。

Comparing with the least squares method, the advantage of this approach in that the influence of non-integer harmonic errors on the estimate of model parameters has been effectively restricted.
