Hk. Garg et Cc. Ko, FAST ALGORITHMS FOR COMPUTING ONE-DIMENSIONAL AND 2-DIMENSIONAL CONVOLUTION IN INTEGER POLYNOMIAL-RINGS, Circuits, systems, and signal processing, 16(1), 1997, pp. 121-139
In a recent work, the factorization properties of polynomials defined
over finite integer polynomial rings were analyzed. These properties,
along with other results pertaining to polymomial theory, led to the d
irect sum property and the American-Indian-Chinese extension of the Ch
inese remainder theorem over such integer rings. The objective of this
paper is to describe algorithms for computing the one- and two-dimens
ional convolution of data sequences defined over finite integer rings.
For one-dimensional convolution, algorithms for computing acyclic and
cyclic convolution are described. For two-dimensional convolution, on
ly the cyclic case is analyzed. Computational and other relevant aspec
ts associated with the structure of these algorithms are also studied.
