Title:
FINITE COMPLEX SIGNAL MEASUREMENT SYSTEM AND HIGH-PRECISION DECOMPOSITION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/016300
Kind Code:
A1
Abstract:
A finite complex signal measurement system and a high-precision decomposition method, particularly a measurement system for a frequency, an amplitude, and an initial phase of a harmonic component of a finite complex signal, comprising a discrete complex source signal extraction module, a discrete complex source signal differential/integral/micro-differential sequence extraction module, and a harmonic component feature decomposition and output module. The discrete complex source signal extraction module converts a source signal into a finite discrete complex source signal according to a feature of the source signal; the discrete complex source signal differential/integral/micro-differential sequence extraction module converts the source signal into a differential/integral/micro-differential sequence of the finite discrete complex source signal according to the feature of the source signal; the harmonic component feature decomposition and output module decomposes and extracts, by using the discrete complex source signal and the differential/integral/micro-differential sequence of the discrete complex source signal and/or an autocorrelation sequence thereof, the frequency, the amplitude, and the initial phase of the harmonic component of the finite complex signal, and outputs same. The problems of measurement and decomposition of a complicated complex signal having a finite length and finite harmonic components are solved, and precise decomposition of noise-free signals and high-precision decomposition of noise signals can be achieved.
