摘要
新型Mark XIIA Mode 5敌我识别系统由美军及北约共同研制,用以提高战场态势感知能力。为提高系统数据传输的抗干扰能力,Mode 5采用了RS(11,9)编译码。文章首先分析了RS码本原多项式及生成多项式,并构建了RS(11,9)伽罗华域,然后给出RS(11,9)编/译码算法。最后利用Simulink仿真平台对RS(11,9)的编/译码过程进行仿真和抗干扰性能分析。
Mark XIIA Mode 5 is a new IFF systerm that was developed by US and NATO to improve the ability of the Battlefield Situation Awareness. In order to improve the abti-jamming capabiolity, Mode 5 uses RS(11,9)encoding /decoding. After the primitive polynomial and the generator polynomial being concluded, Galois field is designed and the detailed algorithm of RS encoding/ decoding is given. RS coding/ decoding is simulated on Matlab Simulink platform, and the anti-jamming performance of RS(31 ,15) is analyzed.
