A novel technique for broadband subspace decomposition

A generalisation of the eigenvalue decomposition (EVD) is proposed for para-Hermitian polynomial matrices. A novel technique for computing this polynomial matrix EVD is outlined. It involves applying a sequence of elementary paraunitary matrices and is referred to as the second order sequential best rotation (SBR2) algorithm. An application of the SBR2 algorithm to broadband subspace identification is briefly illustrated.
