摘　　要：在通信系统中,接收机需要对信道编码进行译码,为了提高信道效率,一般采用具有纠错能力的纠错码来实现编码。在卫星通信中,一般采用卷积码内码和级联码外码联合纠错。首先叙述了卷积码的概念及其译码方法,接着对译码过程进行分析,提出了基于ADSP-BF533的实现方法,最后给出了实验方法及结果。In communication system,channel coding need to be decoded by receivers,in order to improve the channel efficiency,coding is implemented by error-correcting codes which with the ability to correct errors generally.In satellite communication systems,Convolutional code and cascade code are used to error-correcting.The concept of convolutional codes and decoding methods is described first in the paper,and then the process of decoding is analyzed and the implementation method is described based on ADSP-BF533,the experimental methods and results is given at last.
