García Villalba rights: by-nc-nd ispublished: pub subjects: telecomunicaciones subjects: matematicas full_text_status: public pres_type: paper abstract: Nowadays, earth stations for downloading data from LEO (Low Earth Orbit) satellites use large reflector antennas, which pose a number of impairments. In that context, arraying techniques and smart antennas appear as an improvement in performance. This paper presents a comparative study of several beamforming algorithms on a Test-Bed platform, ideas about calibration, robustness topics and some specifics to satellite communications systems such as orbital propagators. All of which will be comprised in a Software Defined Radio (SDR) platform whose description is hereby summarized. For our simulations and measures we will consider the NOAA (National Oceanic and Atmospheric Administration) satellites and more specifically the APT (Automatic Picture Transmission) signal. date_type: published date: 2008-09 place_of_pub: Vélez-Málaga (España) pagerange: 1-4 event_title: XXIII Simposium Nacional de la Unión Científica Internacional de Radio.URSI 2008 event_location: Madrid, España event_dates: 22/09/2008-24/09/2008 event_type: conference institution: Telecomunicacion department: Senales refereed: TRUE isbn: 978-84-612-6290-8 book_title: Actas del XXIII Simposium Nacional de la Unión Científica Internacional de Radio official_url: http://gass.ucm.es/URSI2008/simposium/inicio.html citation: Antón Sánchez, Alberto and Salas Natera, Miguel Alejandro and Martínez Rodríguez-Osorio, Ramón and Torre, Alberto (2008).
