This paper presents a novel transformation technique that can derive various fast Fourier transform (FFT) in a unified paradigm. The proposed algorithm is to find a common twiddle...
An integral part of FFT computation are the twiddle factors, which, in software implementations, are typically stored into RAM memory implying large memory footprint and power cons...
A fundamental question of longstanding theoretical interest is to prove the lowest exact count of real additions and multiplications required to compute a power-of-two discrete Fo...
In this paper, a new fast Hartley transform (FHT) algorithmradix-22 suitable for pipeline implementation of the discrete Hartley transform (DHT) is presented. The proposed algorit...
