抄録(英) The efficient frequency sharing method is issued in present wireless communication world because of the development of various wireless communication terminals and increasing multimedia users. The satellite system uses limited and very precious frequency resources, and it generally has very wide coverage. Therefore, frequency sharing with terrestrial system is necessary for effective managing the wireless communication resources. To achieve the coexistence of both satellite system and terrestrial system, frequency sharing with minimum separation distance scheme is proposed recently. However, it only considers path-loss effect so it can not be an effective method for frequency sharing. In this paper, we will introduce a new method using Cognitive Radio system instead of existing terrestrial network to reduce the interference from terrestrial stations to earth station. The proposed Cognitive Radio system can calculate the interference to satellite system itself and control each transmitter's power. Therefore, the proposed method can reduce interference and also increase frequency reuse factor.
