Abstract
Recently, higher definition broadcasting services such as 4K/8K is required in the satellite link. High-speed and large-capacity satellite link will be required to achieve this demand in the future. One of the means to achieve such link is the use of higher frequency band such as Ka-band (30/20 GHz) for the next-generation broadcasting. However, the attenuation caused by rain gets large in accordance with the frequency. Therefore, it is essential to develop the rain fade mitigation technique as a countermeasure against the rain attenuation. For this reasons, we suggest an adaptive control method using Ka-band multi-beam satellite. In the proposed method, the satellite link is controlled adaptively based on the weather condition. We focus on the Rader-AMeDAS precipitation data as meteorological data for the beam control.
