| Abstract(in English) | A 21-GHz-band satellite broadcasting has been studied to provide advanced broadcasting services such as ultra-high definition TV and multi-program HDTV. To achieve high service availability, mitigation techniques for the large RF signal attenuation due to rain and atmospheric gases are required for the system. In this report, radiation pattern synthesis techniques to aim a high satellite radiation power only to heavily raining areas by using a phased-array antenna and mini-TWTs for the array, as well as a long-block-length interleaving as transmission scheme to compensate the rain attenuation are explained. On-going discussion on the 21-GHz band BSS in ITU is also reported. |
