Abstract
In this paper, we address the problem of blind source separation
of non circular digital communication signals. A new Jacobi-like
algorithm that achieves the joint diagonalization of a set of
symmetric third-order tensors is proposed. The application to the
separation of non-gaussian sources using fourth order cumulants is
particularly investigated. Finally, computer simulations on
synthetic signals show that this new algorithm improves the STOTD
algorithm. |
