Title
Compatibility study on terrestrial radio system operated in the coverage of multi-beam satellite system
Abstract
Studies on frequency sharing techniques have been conducted for the efficient utilization of limited frequency resource. In satellite communications, the frequency sharing with other services is important because the service coverage is generally very wide and overlaps with those of other wireless services. This paper introduces a new method to mitigate interference into the terrestrial stations from the Earth station in the same frequency band by means of band segmentations which are portions of the overall operation frequency band divided by frequency reuse factor. We consider a multi-beam satellite system, where frequency bands are reused in each satellite cell. The terrestrial stations in the satellite cell use band segments of adjacent satellite cells and this may decrease the interferences. In addition, we take the concept of exclusion area in order to enhance the interference mitigation performance. By this way, the terrestrial and satellite systems can share the same frequency bands efficiently. The simulation is performed at frequency reuse factors, seven and three.(1).
