Latest Patents

Ruixian Liu holds a patent for "Frequency domain resampling of time series signals." This patent describes systems, methods, and other embodiments associated with frequency-domain resampling of time series. An example method includes generating a power spectrum for a first time series signal that is sampled inconsistently with a target sampling rate. Prominent frequencies are selected from the power spectrum, and sets of first phase factors that map the prominent frequencies to a frequency domain at first time points are generated. Coefficients are identified that relate the sets of first phase factors to values of the first time series signal at the first time points. Additionally, sets of second phase factors that map the prominent frequencies to a frequency domain at second time points are generated. A second time series signal that is resampled at the target sampling rate is then created by generating new values at the second time points from the coefficients and sets of second phase factors.
