The use of the L1 norm minimization has also been investigated for the more difficult parameter estimation problem A.fi/x …b: (7) For this type of problem it is necessary to determine the parameter vector fias well as the vector x when there are errors in the data vector b. Many signal identification ... Webphones, different methods to perform overdetermined independent vector analysis (IVA) are compared. One method is to select a subset of microphones or all available micro-phones to perform IVA. The second method, the so called subspace method, that utilizes a principal component analysis (PCA) for dimensionality reduction, is applied prior to IVA.
