A general construction of Reed-Solomon codes based on generalized discrete Fourier transform [PDF]
In this paper, we employ the concept of the Generalized Discrete Fourier Transform, which in turn relies on the Hasse derivative of polynomials, to give a general construction of Reed-Solomon codes over Galois fields of characteristic not necessarily co ...

On the computational complexity of the general discrete fourier transform
The complexity of computing the General Discrete Fourier Transform over group algebras of finite groups is studied. Starting with a short introduction to known results, the complexity gains of a new algorithm derived from Clifford's theorem are discussed.

The Chromatic Fourier Transform [PDF]
We develop a general theory of higher semiadditive Fourier transforms that includes both the classical discrete Fourier transform for finite abelian groups at height $n=0$ , as well as a certain duality for the $E_n$ -(co)homology of $\pi

More on algebraic properties of the discrete Fourier transform raising and lowering operators★
In the present work, we discuss some additional findings concerning algebraic properties of the N-dimensional discrete Fourier transform (DFT) raising and lowering difference operators, recently introduced in [Atakishiyeva MK, Atakishiyev NM (2015), J ...

We first show that the real version of the discrete Fourier transform (called RDFT) can be characterized in the framework of polynomial algebras just as the DFT and the discrete cosine and sine transforms.

Properties of continuous Fourier extension of the discrete cosine transform and its multidimensional generalization [PDF]
A versatile method is described for the practical computation of the discrete Fourier transforms (DFT) of a continuous function $g(t)$ given by its values $g_{j}$ at the points of a uniform grid $F_{N}$ generated by conjugacy classes of elements of ...

Numerical Approximation of Probability Mass Functions Via the Inverse Discrete Fourier Transform
First passage distributions of semi-Markov processes are of interest in fields such as reliability, survival analysis, and many others. The problem of finding or computing first passage distributions is, in general, quite challenging.

Duality theory of $p$-adic Hopf algebras [PDF]
We show the monoidal functoriality of Schikhof duality, and cultivate new duality theory of $p$-adic Hopf algebras. Through the duality, we introduce two sorts of $p$-adic Pontryagin dualities.
