A Short Survey on Arithmetic Transforms and the Arithmetic Hartley Transform
R.J.S. Cintra, H.M. Oliveira · Journal of Communication and Information Systems · 2004
Arithmetic complexity has a main role in the performance of algorithms for spectrum evaluation. Arithmetic transform theory offers a method for computing trigonometrical transforms with minimal number of multiplications. In this paper, the proposed algorithms for the arithmetic Fourier transform are surveyed. A new arithmetic transform for computing the discrete Hartley transform is introduced: the Arithmetic Hartley transform. The interpolation process as the key to the arithmetic transform theory is also examined.
