| Abstract(in English) | In recent years, the demand for satellite communications has been increasing, and further capacity enhancement has been required. To address it, we have proposed low earth orbit (LEO) and geostationary (GEO) satellite-based multiple-input multiple-output (LEO-GEO MIMO) transmission. However, in mid-to-high latitude regions including Japan at 35°N, GEO exists at a low elevation angle, making communication capacity lower due to low reception signal power, and the performance improvement is needed. Therefore, this paper proposes LEO-quasi-zenith satellite MIMO transmission to reduce the number of required satellites and to improve throughput characteristics in mid-to-high latitude regions. Numerical results show that the proposed method improves throughput characteristics up to 22% in mid-to-high latitude regions. |
