On underdetermined source separation

  title={On underdetermined source separation},
  author={Anisse Taleb and Christian Jutten},
This paper discusses some theoritical results on underdetermined source separation i.e. when the mixing matrix is degenerate, espcially when there is more sources than observations. In this case, we show that the sources can be restored up to an arbitrary additive random vector. In the particular case of discrete sources, very relevant for digital communications, we show that this vector is certain.
