Research on Transmission Technology of Orbital Satellite Communication System Based on Consistency Algorithm

Communication technology is widely used in urban rail transportation with its advantages of convenient operation and large amount of information, and occupies a large proportion. In rail transportation, communication information transmission system is an important guarantee for communication information security. Communication information transmission system is through the communication system to transmit messages, the choice of safe, reliable, convenient and efficient communication information transmission system is to ensure the information security is an important guarantee, but also the entire railroad “artery”. Only by constantly analyzing and researching, constantly carrying out research, and constantly carrying out technological innovation, can we give full play to its function and its due value. This paper is based on the above problems to explore the consistency algorithm based on the orbit satellite communication system transmission technology, first of all, respectively introduced the consistency algorithm and the orbit satellite communication system, and then through the experiments to verify the consistency algorithm based on the performance of the orbit satellite communication system (in the SNR (Signal-to-Noise Ratio) in the 10dB, the experimental group's PAPR performance of value is around 0.35 and the PAPR value of the control group is around 0.05).
