Complex Convolutions via Fermat Number Transforms

by H. J. Nussbaumer
An approach is described for computing complex convolutions modulo a Fermat number. It is shown that this technique is particularly efficient when the complex convolution is computed by means of Fermat Number Transforms and leads to improved implementation of complex digital filters.
