In the corresponding paper, a generalized Fourier transform is introduced
and its corresponding generalized Poisson summation formula
is derived.
For discrete, Fourier based, signal processing, this
formula shows that a special form of control on the periodic repetitions
that occur due to sampling in the reciprocal domain is possible.
The paper is focused on the derivation and analysis of
a weighted circular convolution theorem. We use this specific result
to compute linear convolutions in the generalized Fourier domain,
without the need of zero-padding. This results in faster, more resource-
efficient computations.
