Viterbi译码性能分析及路径存储长度影响的研究

Analysis of viterbi decoding performance and studying the effect of path memory length

论述了卷积码Viterbi译码误码率性能的分析方法。通过对计算机仿真所得数据的分析表明路径存储长度对译码性能的影响有限。同时还研究了利用生成函数分析路径存储长度对译码性能影响的方法和局限性。讨论了影响译码性能的可能存在的一些因素。

This paper presents a method of analysis bit-error-rate performance for Viterbi decoding of convolutional code . The computer simulation shows that the decoding performance is limited with adding the path memory length. The common method has its limitations when using the generating function to analyze decoding performance (especially in an upper bound on the bit-error-rate ). Discussing a few of potential factors that affect decoding performance.
