Embodiment Construction
[0087] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0088] At present, typical harmonic elimination schemes are divided into frequency domain and time domain. figure 1 It is a solution of frequency domain harmonic elimination in the prior art. Such as figure 1 As shown, the frequency-domain harmonic elimination first transforms the received signal into the frequency domain through Fourier Transform (FFT for short), and then counts the power of each frequency point signal and judges it with a preset thresho...
