综述短波通信中的差错控制以及有效的纠错编码技术在自适应通中的应用,提出在自适应通信中最有效的译码方法是软判决译码,效果较佳的纠错编码是扩展的GOLAY码、(24,12:8)纠错编码和级连码。文中以(23,12:7)GOLAY分组码为例,采用嵩忠雄译码器电路,较详尽地对GOLAY码的译码方法进行了论述,指出了(23,12:7)纠错编码的不足之处;最后对码的修改进行了概述。
This paper summarizes the error control in shortwave communication and the application of effective error correction coding technology in adaptive communication. It is proposed that the most effective decoding method in adaptive communication is soft decision decoding, and the better error correcting coding is extended GOLAY code, (24,12: 8) error correction coding and cascading code. Taking the (23,12: 7) GOLAY block code as an example, the Songzhongxiong decoder circuit is used to discuss the decoding method of GOLAY codes in detail. It is pointed out that (23,12: 7) error correction coding Shortcomings; Finally, the code changes are outlined.
