Abstract(in English) In this paper, the possibility of satellite communication systems using a multiband UWB signal format is considered. For terrestrial short-distance high-speed communications, multiband UWB schemes are proposed in IEEE 802.15 TG3a and the discussion is ongoing at the standardization body. In the multiband UWB scheme, frequency hopping is adopted over 3.1 - 10.6 GHz, which is regulated by the FCC (Federal Communication Commission) of the U.S.A., and the bandwidth of one hopping spectrum (subband) is about 500 MHz. Multiband technology inherently has some suitable characteristics for terrestrial UWB such as applicability to variable transmission rates, avoidance of harmful interference to other systems, simple localizability of frequency allocations, and so forth. In this paper, a satellite communication downlink employing the multiband UWB signal transmission is considered. The total bandwidth is assumed to be 500 MHz in the allocation of the satellite downlink and it is divided into multiple subbands. We report the initial results of the study on the link budget calculation and the estimation of the signal transmission speed assuming multiband UWB signal transmission from a GSO satellite to the earth's surface.
