An efficient Jacobi-type algorithm for blind equalization of paraunitary channels

Blind equalization of convolutive mixtures is often done by resorting to methods based on higher order statistics. Under the assumption that the data have been pre-whitened the problem reduces to the estimation of paraunitary channels. The method PAJOD was developed to equalize paraunitary channels in [8]. Our contribution is an efficient implementation of the PAJOD algorithm which is called PAJOD2. Comparisons between PAJOD and PAJOD2 based on computer simulations will also be reported.
