TL;DR: In this paper, the optimal design of M-channel perfect reconstruction FIR quadrature mirror filter (QMF) banks based on the orthogonal matrix concept is presented. But this method is not suitable for the MIMO channel.
Abstract: A new method is presented for the optimal design of M-channel perfect reconstruction FIR quadrature mirror filter (QMF) banks which is based on the orthogonal matrix concept. The parameters of the analysis filters are adjusted so that they have a linear phase and minimum stopband energy. Comparison with a recently published method reveals that the resulting design procedure gives better stopband characteristics. A numerical design example is included to validate the theory and to demonstrate the superiority of the designed filters from selectivity, reconstruction and distortion points of view.
