| "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, antenna 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 and ideas about the calibration and signal tracking topics. The overall structure is based upon a software defined radio (SDR) receiver. 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. | |
