摘要
介绍了截尾卷积码的循环维特比译码算法和BCJR译码算法,以及在循环维特比算法基础上改进的环绕维特比译码算法和双向维特比算法,最后对各种译码算法的性能进行了仿真分析。
In this paper, the circular Viterbi algorithm（CVA） and BCJR algorithm for tail-biting convolutional codes（CC） decoding are introduced. The wrap-around Viterbi algorithm（WAVA） and bidirectional Viterbi algorithm（BVA） which were based on CVA are introduced in detail. The performances of these decoding algorithms are analyzed at last.
