| Abstract(in English) | This paper proposes a novel interception tolerability improving technique for existing satellite earth stations. When demodulators receive amplitude and/or phase distorted signal, their receiving characteristics generally degrade. We focus on this phenomenon and realize to form phase distorted signal using a spectrum editing technique that have been studied by NTT laboratories. As a regular user knows the distortion characteristics, he can compensate the distortion and appropriately demodulate. By contrast, as eavesdroppers do not know the distortion characteristics, their receiving characteristics witheringly degrade. To verify our proposed technique, we conducted indoor experiments and confirmed that the proposed technique offers good performance. |
