Research on Error Correction of State Data Transmission System of Moving Carrier Based on Beidou Short Message

With the development and application of the communication system based on Beidou short message, how to ensure the accuracy of the transmission information is one of the research hotspots in recent years. This paper introduces several existing error correction technologies for audio and video communication information transmission, which can be summarized into three categories: automatic repeat request technology, forward error correction technology and hybrid error correction technology, and analyzes the design principle, practical application performance, advantages and disadvantages of each technology. This paper provides reference for the design of error correction part of audio and video information transmission system based on short message communication.
