Multidimensional parallel processing methods for rational sampling lattice alteration
Shogo Muramatsu, Hitoshi Kiya · 2002
In this paper, we propose two multidimensional parallel processing methods for rational sampling lattice alteration. Our proposed methods enable us both to implement the rational lattice alteration with the parallel processor approach and to eliminate the redundancy caused by up- and down-sampling. Those methods are provided by extending two conventional block processing techniques for FIR filtering: the overlap-add method and the overlap-save method, respectively.
