Tipo tesi MASTER THESIS
Descrizione Compressed sensing, developed in harmonic analysis and signal processing, aims at reconstructing a signal sampled at a frequency lower than the one of the Shannon-Nyquist theorem, when information about the sparsity of the signal is known(1). The framework has been recently used also to address problems of antenna array design(2).
The thesis will explore this connection in the depth, in particular investigating the possibility of using Discrete Prolate Spheroidal Sequences(3) to approximate the desired pattern.
