摘要
(2,1,7)卷积码作为差错控制手段在卫星通讯领域得到了广泛应用。本文研究并实现了一种软件方式的基于(2,1,7)卷积编码的维特比译码(Viterbi)解决方案,测试结果表明,该方案能够使得误码率为10-3量级的数据经译码处理后误码率降低到10-6,可以满足维特比译码应用需求。
The (2,1,7) convolutional code,as the recommended standard by CCSDS,has been applied widely in the field of communication. This paper presents a software implementation of Viterbi decoding for (2,1,7) convolutional code. The result shows that this kind of Viterbi decoding algorithm is able to decrease the bit error rate from 10-3 to 10-6 and thus it can be used for error control.
