Spatially constrained parallel factor analysis for semi-blind beamforming


Parallel factor analysis (PARAFAC) has found numerous applications in blind signal processing, mainly due to its nice identifiability. However, the standard PARAFAC decomposition does not use prior information on the mixing procedure, which could actually be roughly estimated. As a result, the standard PARAFAC is ambiguious in permutation, and may converge… (More)
