WebFeb 17, 2024 · In this paper, we investigate singular spectrum analysis (SSA) as an analysis tool for radio data. We show the intimate connection between SSA and Fourier techniques. We develop the relevant mathematics starting with an idealized periodic dataset and proceeding to include various non-ideal behaviours. WebSingular Spectrum Analysis (SSA) is a non-parametric procedure based on subspace algorithms for signal extraction [1]. The main task in SSA is to extract the underlying signals of a time series like the trend, cycle, seasonal and irregular components. It has been applied to a wide range of time series
