| Abstract(in English) | Following the development of the Big-LEO systems such as Iridium, ICO, and Globalstar, BroadBand-LEO systems such as Teledesic and SkyBridge, which focus on high-speed data services using Ka-band LEO, have been proposed and attacts attention. In BroadBand-LEO systems, "Fixed-Earth Cell" is proposed, which consists of rectangular cell attached to the Earth's surface and the user traffic in a cell is accommodated by one spot-beam of a satellite that can illuminate the cell. On the other hand, we have proposed "User-Dedicated Cell" to be exclusively illuminated by one spot-beam of a satellite for one traffic This paper provides numerical comparison between User-Dedicated Cell and Earth-Fixed Cell and shows the superiority of the User-Dedicated Cell. The compatibility of User-Dedicated Cell with Multiple Access Methods is also demonstrated and discussed from the viewpoint of the number of users that can be accommodated to the system. |
