Abstract

An effective optimization algorithm is developed to design multi-dimensional recursive phase equalizers. The optimization algorithm uses an iterative procedure to minimize the maximum group delay ripple. The criteria used to guarantee the stability of the equalizer is based on DeCarlo-Strintzis theorem. Using this technique, the algorithm can be used in higher dimensions with less intensive computations. Illustrative examples are included to show the effectiveness of the algorithm.
