摘要
RS码是一种纠突发错误能力很强的分组循环码,DFH是一种集跳频图案、信息调制、解调于一体的具有较强的抗跟踪干扰能力的新型跳频技术,在分析RS码及DFH性能的基础上,通过计算机仿真具体分析基于RS码的DFH系统的BER性能。与以往论文相比,比较了不同编码下的系统性能,由仿真结果可知,BER为时采用(31,15)RS码比不采用RS码可得到近2dB的增益。
R-S codes are a kind of channel coding which have strong ability to correct abrupt error,differential frequency hopping(DFH,) is a new frequency hopping technique,which has strong ability of anti tracking interference.Based on the performance of R-S codes and DFH system,use the results of the simulation,the performance of DFH system based on RS codes is analyzed on the whole system.The BER prformances are discussed in different coding modes,when the BER is ,use the (31,15)R-S codes can get 2dB enhance.
