dc.description.abstractSatellite communication is a valuable option in regions having low population densities, where mobile users do not have access to terrestrial communication systems. In this thesis, the design considerations of multi-beam satellite CDMA systems are treated. In communication systems, higher capacities can be obtained by efficiently using the available frequency spectrum. Satellite systems can achieve the high spectrum efficiency by using multi-beams. The first issue emphasized in this thesis is that of co-channel interference in multi-beam systems. Similar to the terrestrial systems, in multi-beam satellite systems co-channel interference is created by interfering users within the wanted user's own cell as well as users in the other cells using the same operational frequency. Another important issue in applying the CDMA scheme is the problem of unequal received power levels. The performance of a multi-beam satellite CDMA system using perfect and imperfect power control are calculated and compared. (Abstract shortened by UMI.)
