Spiral FFT: An efficient method for 3-D FFTS on spiral MRI contours
The Fast Fourier Transform (FFT) allows the Discrete Time Fourier Transform (DTFT) to be efficiently sampled on a uniform grid in frequency. In many applications, including Magnet...

Periodic Plus Smooth Image Decomposition
When the Discrete Fourier Transform of an image is computed, the image is implicitly assumed to be periodic. Since there is no reason for opposite borders to be alike, the “peri...

The finite harmonic oscillator and its applications to sequences, communication and radar
A novel system, called the oscillator system, consisting of order of p 3 functions (signals) on the finite field p; with p an odd prime, is described and studied. The new functions...
