Title
Coexistence Downlink Interference Analysis Between LEO System and GEO System in Ka Band
Abstract
With the development of satellite communication techniques, various types of new service have been emerging, which leads to more spectrum resource requirements. However, traditional L(1–2GHz)/S(2–4GHz) bands which are allocated to satellite communications are limited, and these bands cannot meet the increasing bandwidth demands. Therefore, the Ka(27–40GHz) band has attracted the attention of many satellite communication institutes due to the large bandwidth. With the implementation of many Geostationary Earth Orbit (GEO) and Low Earth Orbit (LEO) constellation plans in Ka band, the coexistence interference analysis between LEO and GEO system is important. In this paper, the coexistence downlink interference between LEO system and GEO system is analyzed, and the impact of the exclusive angel strategy on the inference is evaluated. Simulation results show that the exclusive angel strategy can reduce the in-line downlink interference from LEO to GEO. However, it decreases the coverage of LEO. In addition, Simulation results show that there is little downlink interference from the GEO to LEO.
