Abstract:

Based on the air-to-air missile telemetry system characteristics,the RS code cascade CRC code is selected as the channel coding of the telemetry system.A brief introduction is given to the two coding theories,and the design methods and implementation results of the telemetry system RS cascade CRC code.The experiments show that RS and CRC concatenated coding at the sending end of the telemetry system helps improve the reliability of telemetry data,and the data error correction capability has been strengthened while the efficiency of real-time decoding of the receiving end software is substantially increased.
