초록
Co-existence of various wireless systems may cause frequency interference problems. For this reason, frequency sharing studies play a very important role in order to use limited spectrum resources efficiently. Because a satellite system covers a global area in nature, the frequency sharing between the satellite and terrestrial systems is essential. For satellite systems using Ka bands, we can increase spectrum efficiency by considering offaxis angles of the earth station antennas. In this paper, we demonstrate the analysis results of the separation distance between the satellite earth station and a terrestrial station with random height. By using these results, we can design and implement Ka band wireless systems with the optimum separation distances, and this will lead efficient use of limited frequency spectrum resources. © 2008 IEEE.
