虽然维特比译码在实际系统中得到了广泛的应用，但对其准确的误码性能的研究却很少。我们已经提出了一个2状态的软判决维特比解码的分析技术。在本文中，这种技术被扩展到四状态软判决维特比译码的误比特概率。这采用路径度量的概率密度函数（PDF）的迭代计算。
Although Viterbi decoding is widely used in practical systems, only a few studies have been made for the exact error performance. We already proposed analytical technique for a 2-state soft decision Viterbi decoding. In this paper, this technique is extended to bit error probability for 4-state soft decision Viterbi decoding. This employs an iterative calculation of probability density function (PDF) of the path metrics.
