Blind Separation of Nonstationary Sources in Noisy Mixtures

  title={Blind Separation of Nonstationary Sources in Noisy Mixtures},
  author={Seungjin Choi and Andrzej Cichocki},
In this letter we develop a new method of blind source separation that is not sensitive to additive white noise. Our method exploits the nonstationarity and temporal structure of sources. The method needs only multiple time-delayed correlation matrices of the observed data at several di erent time-windowed data frames to estimate the mixing matrix. The implementation using joint diagonalization (JD) is described. Simulations verify the high performance of the proposed method, especially in low… CONTINUE READING
