activity-recognition--based-on-hmm
- 一种HMM可以呈现为最简单的动态贝叶斯网络。隐马尔可夫模型背后的数学是由LEBaum和他的同事开发的。它与早期由RuslanL.Stratonovich提出的最优非线性滤波问题息息相关，他是第一个提出前后过程这个概念的。 在简单的马尔可夫模型（如马尔可夫链），所述状态是直接可见的观察者，因此状态转移概率是唯一的参数。在隐马尔可夫模型中，状态是不直接可见的，但输出依赖于该状态下，是可见的。每个状态通过可能的输出记号有了可能的概率分布。因此，通过一个HMM产生标记序列提供了有关状态的一些序

viterbi_deco
- Viterbi decoding of convolutional code with half rate & four state. It can done by two matrics . that is branch metrics and path metrics. Branch metrics is hamming distance between the parity bits and received bits. If branch metrics is zero then no
线性卷积编码的线形移位寄存器poly2trellis的解释
- 线性的卷积编码，基本的信道编码，可以由线性移位寄存器（即线性多项式）构成。 输出网格trellis表示由移位寄存器组成的网格装的卷积编码器，通过移位寄存器多项式生成，所以在Matlab中的函数叫做poly2trellis，也就是多项式poly-to-网格trellis，用来描述寄存器的结构方式。生成的trellis可以作为线形卷积编码函数convenc和或者其解码（如Viterbi解码函数vitdec）的输入。
