Blind Separation of Underwater Acoustic Signals [PDF]
, 2006 In last two decades, many researchers have been involved in acoustic tomography applications. Recently, few algorithms have been dedicated to the passive acoustic tomography applications in a single input single output channel. Unfortunately, most of these algorithms can not be applied in a real situation when we have a Multi-Input Multi-Output channel.

Estimating functions for blind separation when sources have variance-dependencies
, 2022 S.136-143The blind separation problem where the sources are not independent, but have variance-dependencies is discussed. Hyvarinen and Hurri[1] proposed an algorithm which requires no assumption on distributions of sources and no parametric model of ...
