WebApr 11, 2024 · The major advantage of using singular spectrum analysis in the present work is that it can reliably isolate and extract the very low-amplitude nonlinear sensitive components (super harmonics and intermodulation) being buried in the total response based on the pairwise eigenvalue property of harmonic components. Investigations have been … WebTo eliminate this disadvantage, the new circulant sin-gular spectrum analysis was proposed by Bógalo in 2024 (Bógalo et al. 2024). Circulant singular spectrum analysis is a nonparametric signal decomposition approach that may rebuild a time series as the sum of orthogonal components of known frequencies (Bógalo et al. 2024). The main advantage
WebJan 8, 2024 · Singular Spectrum Analysis (SSA) is a nonparametric tecnique for signal extraction in time series based on principal components.
