Fourth order autodidact identification method and device for identifying an underdetermined mixture of signals

摘要

a method for the identification of the signatures of at least four two sources in a system comprising a number of sources p and a number n of reception sensors receiving the observations, said sources with different spectra, comprising at least three stages: your:- a bleaching stage to the order 4 of the comments received on the receiving sensors to orthonormaliser steering vectors in the matrices of source quadricovariance representations used.- a joint diagonalization of several matrices, stage of quadricovariance bleached in order to identify the spatial signatures of the sources;application to a communication network
