Spectral Intersections for Non-Stationary Signal Separation

  title={Spectral Intersections for Non-Stationary Signal Separation},
  author={Trausti T. Kristjansson and Thad Hughes},
We describe a new method for non-stationary noise suppression that is simple to implement yet has performance that rivals far more complex algorithms. Spectral Intersections is a model based MMSE signal separation method that uses a new approximation to the observation likelihood. Furthermore, Spectral Intersections uses an efficient approximation to the expectation integral of the MMSE estimate that could be described as unscented importance sampling. We apply the new method to the task of… CONTINUE READING
