摘要
为提高抗干扰能力,JTIDS在数据部分采用了RS(31,15)编译码。在分析了RS码本原多项式及生成多项式的基础上,构建了RS(31,15)的伽罗华域,给出RS(31,15)的编/译码的具体算法。在Simulink仿真平台上对RS(31,15)的编/译码过程实现了仿真。通过仿真结果,具体分析了RS(31,15)的抗干扰性能。
In order to improve anti - jamming capability, JTIDS uses RS（31,15） coding/decoding in data. After the primitive polynomial and the generator polynomial being concluded,GF（25） is designed and the detailed algorithm of RS coding/decoding is given. RS coding/decoding is simulated on Matalab Simulink platform. Based on the result of simulation, the antijamming performance of RS（31,15） is analyzed.
