摘要

介绍了ＣＨＩＲＰ调制解调器的特点，对ＣＨＩＲＰ调解器采用的ＧＯＬＡＹ（２４，１２）码的软判译码方法进行了讨论，提出了一套快速灵活的软判译码综合优化方案，对方案的编码增益进行了测试，结合短波信道的误码率估值技术，利用软判译码器的输出实现了对误码率参数快速、准确的估计．

Abstract

The characteristic of a new type of HF ALE modem

CHIRP modem is introduced first.Then the algorithm of soft decision decoding of Golay （24

12） used in this modem is discussed.We synthesized some techniques to design a fast and flexible scheme of soft decision decoding.The decoding time and coding gain of this scheme are tested under on HF channel simulator

and the result of test is satisactory.We also raised a new scheme to evaluate PBER

one of the most important we analyzed the characteristic of PBER evaluation according to the simulation results and discussed some schemes to improve the performance of PBER evaluation.
