This paper considers the problem of sparse spectrum blind reconstruction and its constituent narrow band (bandwidth not exceeding B Hz) source direction of arrival (DOA) estimation, at sub-Nyquist sampling rates and with an M element uniform linear array. We propose a modification to the receiver architecture by adding an M channel delay network to only the first sensor element. This delay network in practice can simply be realized by cascading M identical delays. Further, a novel ESPRIT based… CONTINUE READING
