Research on Transmission Technology of Low-Orbit Satellite Communication System Based on 5G
Transmission is an important link in the operation process of low-orbit satellite communication system,but the application effect of the current transmission technology is not ideal.Not only the bit error rate is relatively high,but also the transmission throughput of the communication system is low.Aiming at the shortcomings of the current technology,the transmission technology of the low-orbit satellite communication system based on 5G is proposed.The frequency domain equalization method is used to detect the user signal of the uplink of low-orbit satellite communication,and compensate the error signal.The downlink channel of the communication system is estimated by using 5G technology,signal interference is eliminated,and the transmission of the low-orbit satellite communication system based on 5G is realized.The experimental results show that the transmission error rate of low-orbit satellite communication system is less than 1%,and the system throughput is more than 40Mbps.The design technology has a good application prospect in the field of low-orbit satellite communication.
