Computer model of satellite communication channel of high-throughput satellite in medium Earth orbit system with second generation satellite extensions and orthogonal frequency-division multiplexing technologies

The paper presents the results of constructing a computer model of the satellite communication channel of the high-throughput satellite in medium Earth orbit system with second generation satellite extensions and orthogonal frequency division multiplexing technologies. The most promising areas of research in this area are identified and analyzed. The operation of the constructed system in various interference conditions is analyzed and the influence of the Doppler shift on the operation of the communication line is investigated. A comparison with other existing configurations of the satellite communication channel is made. Based on the results of the study, the advantages and disadvantages of the proposed configuration of satellite communication of the high-throughput satellite in medium Earth orbit system with second generation satellite extensions and orthogonal frequency-division multiplexing technologies are revealed.
