Satellite link analysis and antenna effect on satellite ecommunications

This paper presents the performance of satellite communication system using ۱۶QAM digital modulation technique for X-band. This digital modulation method provides a high data rate in transmission without increasing the bandwidth comparedto other digital modulation methods. The purpose of this article is to explain, analyze the satellite link and the effect of the antenna on the satellite, so it explainsdigital modulation with high data rate in transmission without increasing the bandwidth compared to other digital modulation methods. The current method of statistical community research is sampling and virtual space tools, validation and finalreview and diagnostic analysis that analyzes the satellite link and the effect of theantenna on the communication satellite. The findings are: Channel Model, Antennas, Passive Antennas, Active Antenna Arrays, Ul-tra high Throughput Satellites, ۵GNetworks, Simulation Results. The results are, this digital modulation method offersa high data rate in transmission without increasing the bandwidth compared toother digital modulation methods. And applications are developed in Matlab environment and the obtained results such as power figures, constellation diagramsand BER ratio for types such as ۴, ۸, ۱۲, ۱۶ GHz are discussed.
