Spectral Representation of Two-Sided Signals from and Applications to Signal Processing

Signal processing tools working directly on encrypted data could provide an efficient solution to application scenarios where sensitive signals must be protected from an untrusted processing device. In this paper, we consider the data expansion required ...

This paper represents a signal adaptive two-dimensional (2-D) method for space/spatial-frequency (S/SF) signal analysis. The method is capable of taking a variable number of execution steps (the only necessary ones regarding desirable--2-D Wigner ...

We study the distributed processing of graph signals that are well represented by graph spectral dictionaries. We first analyze the impact of quantization noise in the distributed computation of polynomial dictionary operators that are commonly used in ...
