Ss. Kidambi et Rp. Ramachandran, COMPLEX COEFFICIENT NONRECURSIVE DIGITAL-FILTER DESIGN USING A LEAST-SQUARES METHOD, IEEE transactions on signal processing, 44(3), 1996, pp. 710-713
In this correspondence, a method for the design of complex-coefficient
nonrecursive filters is described. In this method, a mean-square erro
r is formulated in a quadratic form, The filter coefficients are obtai
ned by solving a system of linear equations using computationally robu
st and efficient algorithms. Examples are presented to demonstrate the
efficacy of our method.
