Radix-2 Fast Hartley Transform Revisited
H. M. de Oliveira, V. L. Sousa, H. A. N. +1
A Fast algorithm for the Discrete Hartley Transform (DHT) is presented, which resembles radix-2 fast Fourier Transform (FFT). Although fast DHTs are already known, this new approac…
The Discrete Cosine Transform over Prime Finite Fields
M. M. Campello de Souza, H. M. de Oliveira, R. M. Campello de Souza +1
This paper examines finite field trigonometry as a tool to construct trigonometric digital transforms. In particular, by using properties of the k-cosine function over GF(p), the F…
New Algorithms for Computing a Single Component of the Discrete Fourier Transform
G. Jerônimo da Silva, R. M. Campello de Souza, H. M. de Oliveira
This paper introduces the theory and hardware implementation of two new algorithms for computing a single component of the discrete Fourier transform. In terms of multiplicative co…
