The discrete Fourier transform: A canonical basis of eigenfunctions
We exhibit a canonical basis of eigenvectors for the discrete Fourier transform (DFT). The transition matrix from the standard basis to defines a novel transform which we call ...

Implementation of message-passing algorithms for the acquisition of spreading codes
A new technique to acquire pseudo-noise (PN) sequences has been recently proposed in [1] and [2]. It is based on the paradigm of iterative Message Passing (iMP) to be run on loopy...

The Ordinal Recursive Complexity of Lossy Channel Systems
We show that reachability and termination for lossy channel systems is exactly at level Fωω in the Fast-Growing Hierarchy of recursive functions, the first level that dominates...
