| Abstract(in English) | Recently, in order to improve the exhaustion of the frequency in the terrestrial network, satellite and terrestrial network combination system have been attracted much attention. In this combination system, the assigned frequency band of satellite communication is distributed to satellite and terrestrial network, so it is possible to improve the problem. Also, the area such as mountain region and sea is hard to deploy the base stations. Since satellite has broad coverage, users can communication with satellite there. Furthermore, if terrestrial infrastructure is destroyed when the natural disaster strikes, there is big demand to communicate but many users cannot communicate with someone. In this time, satellite have no damage because it is in space. Therefore many users can reliable communicate with someone. In frequency distribution, the exhaustion of the frequency is improved when the frequency band is distributed to terrestrial network. However, in the case satellite and terrestrial network is distributed the duplicate frequency band, the interference occur and frequency efficiency is decreased in the combination system. In this study, we propose a determination of the frequency distribution for maximizing frequency efficiency considering interference in satellite and terrestrial network combination system. |
