Abstract:
A signal feature extracting method and apparatus is disclosed. The signal feature extracting apparatus estimates element signals forming an input signal using a signal model to be determined by parameters, and extracts signal features using the estimated element signals. The method of extracting a signal feature including estimating element signals from an input signal, and extracting a signal feature using the estimated element signals, wherein the estimating of the element signals comprises estimating a first element signal of the input signal, and estimating a second element signal based on a waveform of a first intermediate signal, the first intermediate signal being a signal derived from the first element signal eliminated from the input signal.
