Theory and design of two-dimensional DFT modulated filter bank with arbitrary modulation and decimation matrices ?
The PR condition is derived for the 2D general DFT modulated filter banks. Spatial domain condition of PR is derived to facility filter bank design. 2D NPR DFT modulated filter banks with good overall performance are designed.
