| Abstract(in English) | Multiple access technologies have been required for intersatellite communications between low earth orbit (LEO) satellites and geostationary orbit (GEO) satellites. In the multiple accesses due to multiple-beam antennas, insufficient isolations between individual beams lead to interferences and they cause bit error degradations. To suppress the effect of interference between the beams, null beam forming by phase control of each antenna element is studied. However, it is known that there is limited interference suppression position. In this report, to suppress the interferences, null beam forming by using digital beam forming technology is studied. Computer simulations indicate that multiple nulls can be formed by amplitude and phase control of each antenna element and the gain reduction due to it are investigated in detail. Some experiments validate the simulations. |
