A one stage self-adaptive algorithm for source separation

摘要: In order to perform separation of a mixture sources, an interesting approach is maximise contrast function: e.g. the Comon. This paper brings two novel contributions (i) algorithm as proposed in adaptively Comon's contrast. However it requires preprocessing whitening operation which awkward when ill-conditioned. (ii) A new criterion defined that free prewhitening step. case sources can be proved this also maximized and has additional advantage not require identical signs for fourth-order cumulants sources. Achievement these adaptive algorithms demonstrated using performance index. >
