Patent ID: 7079988

Claim:
A method of blind identification of sources within a system including P sources and N receivers, comprising the steps of: identifying the matrix of direction vectors of the sources from the information proper to the direction vectors a p of the sources contained redundantly in the m=2q order circular statistics of the vector of the observations received by the N receivers, wherein the m=2q order circular statistics are expressed according to a full-rank diagonal matrix of the autocumulants of the sources and a matrix representing the juxtaposition of the direction vectors of the sources as follows: C m,x =A q ζ m,s A q H where ζ m , s = diag ⁡ ( [ C 1 , 1 , … ⁢ , 1 , s 1 , 1 , … ⁢ , 1 , … ⁢ , C P , P , … ⁢ , P , s P , P , … ⁢ , P ] ) is the full-rank diagonal matrix of the m=2q order autocumulants C p , p , … ⁢ , p , s p , p , … ⁢ , p des sources, sized (P×P), and where A q = [ a 1 ⊗ ( q - 1 ) ⊗ a 1 * ⁢ ⁢ … ⁢ ⁢ a p ⊗ ( q - 1 ) ⊗ a p * ] , sized (N q ×P) and assumed to be of full rank, represents the juxtaposition of the P column vectors [ a p ⊗ ( q - 1 ) ⊗ a p * ] .
