自适应选频技术是短波通信的一大高新技术,特别适用于军事通信领域。其中采用的Golay码是一种纠错能力很强的码字,它应用于自适应选频系统中的HFmodem的模块中。研究了在自适应选频通信系统中Golay码的编译码原理,以军标GJB2077-94为基准探讨了如何采用DSP芯片(TMS320C54x)实现Golay码的编译码,并给出了实现的框图及流程图。 Adaptive frequency selective technology is a high-tech shortwave communications, especially for military communications. The Golay code used therein is a kind of code word with strong error correction capability, which is applied to the HFmodem module in the adaptive frequency selection system. The coding principle of Golay code in adaptive frequency-selective communication system is studied. Based on the military standard GJB2077-94, the coding and decoding of Golay code using DSP chip (TMS320C54x) is discussed. The block diagram and flow chart of the implementation Figure
