强烈推荐好用的卷积码编码，维特比译码和软判决，本代码简易可行。

隐马尔可夫的模型的经典实现的c代码。包括前向，后向，veitebi算法等。-Hidden Markov model of the classic implementation of the c code. Including forward, backward, veitebi algorithm.

veitebi编译码，比较64QAM、16QAM、QPSK等的误码率关系(Veitebi encoding and decoding, compared to 64QAM, 16QAM, QPSK and other bit error rate relationship)
