APPLICATIONS OF GNSS SIGNAL CHARACTERISTICS ANALYZED BY FAST FOURIER TRANSFORM

摘要

The present invention relates to applications of GNSS signal characteristics analyzed by fast Fourier transform. The present invention relates to an application method which minimizes signal quality degradation due to a multi path by applying FFT to identify signal characteristics, quantifying altitude changed to a multi-tone using local spectra results, and reflecting the same to a signal processing technique when a single-tone signal composed of a single signal is changed to the multi-tone signal due to the multi-path.;COPYRIGHT KIPO 2020
