A Matrix Laurent Series-based Fast Fourier Transform for Blocklengths N=4 (mod 8)
H. M. de Oliveira, R. M. Campello de Souza, R. C. de Oliveira
General guidelines for a new fast computation of blocklength 8m+4 DFTs are presented, which is based on a Laurent series involving matrices. Results of non-trivial real multiplicat…

Multilayer Hadamard Decomposition of Discrete Hartley Transforms
H. M. de Oliveira, R. J. Cintra, R. M. Campello de Souza
Discrete transforms such as the discrete Fourier transform (DFT) or the discrete Hartley transform (DHT) furnish an indispensable tool in signal processing. The successful applicat…
