| Abstract(in English) | For future Japanese Low Earth Orbit (LEO) constellation satellite communication, explore of new frequency band (Q/V-band) in millimeter-wave is required. Relatively large number of flexible beams are also required. As the result, Q/V-band on-board digital beam forming (DBF) antenna system based on array antenna should be developed. In this paper, outline of proposed Q/V-band LEO constellation satellite communication system and transceiver architecture based on direct digital RF are described. In the case of digital rich direct digital RF transceiver, the size of digital signal processor becomes a problem. To solve this, a new DBF system using split array-antennas is proposed and the reduction of computational complexity is confirmed. |
