| Abstract(in English) | In many earth-orbital satellite communication systems with cellular concept, each satellite uses mulibeam antenna to project many beams onto the earth to from cells.The amount of multiple access interference depends on the radiation pattern of the beams. In this paper, we consider the up-link in CDMA system and evaluate the effect of beam pattern on the system capacity such as the maximum number of channels and erlang capacity. We have shown the relation between beam pattern and capacity per cell. As a result, it is found that the system capacity is dominated by the property of the cells formed at the edge of the service area of a satelite. |
