摘要
针对空空导弹遥测系统的特点,选择RS码级联CRC码作为遥测系统的信道编码,分析了两种编码的原理,介绍了遥测系统中RS级联CRC码的设计方法及实施效果。并通过实验证明,将RS与CRC进行级联编码后加入遥测系统发送端,有助于提高遥测数据的可靠性,在数据纠错能力得到加强的同时系统接收端软件实时解码效率也大幅提高。
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 te- lemetry 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.
