    Solution and cost analysis of general multi-channel and multi-stage filtering circuits
    (IEEE, 1998-10) Kutay, M. Alper; Arıkan, Orhan; Özaktaş, Haldun M.; Erden, M. F.; Özaktaş, Hakan
    The fractional Fourier domain multi-channel and multi-stage filtering configurations that have been recently proposed enable us to obtain either exact realizations or useful approximations of linear systems or matrix-vector products in many different applications. We discuss the solution and cost analysis for these configurations. It is shown that the problem can be reduced to a least squares problem which can be solved with fast iterative techniques.
