In satellite communication, Spatial Division Multiple Access (SDMA) has become one of the most promising techniques that can accommodate continuing increase in the number of users and traffic demands. The technology is based on radio resource sharing that separates communication channels in space. It relies on adaptive and dynamic beam-forming technology(More)
—Spatial Division Multiple Access (SDMA) is a principle of radio resource sharing that separates communication channels in space. It relies on adaptive and dynamic beam-forming technology and well-designed algorithms for resource allocation. As satellite communication systems move towards greater capacity in both the number of users and throughput, SDMA(More)
In this paper, we investigate models and methods for solving real-life frequency assignment problems based on scheduling theory. If we assume binary interferences, a multiple carrier frequency assignment problem can be treated as a disjunctive scheduling problem since a user who requests a number of contiguous frequencies can be considered as a(More)
