speech recognition matlab code

产生MDPSK信号的matlab源代码，分为4dpsk和8dpsk两种(MDPSK signals generated matlab source code is divided into two 4dpsk and 8dpsk)

说明：  MATLAB7的官方学习手册。全英文的哦。详细的教程，值得一读。(MATLAB7 official study manual. Oh, the whole of English. Detailed tutorial, worth reading.)

上述代码对光纤通信系统中的常用NRZ码时域和频域特性进行了分析，NRZ适于短距离低速率光纤通信系统中使用，其频谱特性相对于RZ码频谱较窄，但峰值功率较高，对非线性容忍度较小(NRZ,modulation,PMD analysis)

说明：  CNM算法实现的快速社团检测，方便快捷好用(CNM Fast community detection based on the algorithm is convenient, fast and easy to use.)

基于matlab语言环境下的暂态上机计算对称电流和不对称电流故障的计算(Based on the transient in the matlab language environment on the calculation of the symmetrical current and asymmetrical current fault)

airborne inertial-SLAM 是目前无人机在未知环境中实现导航的重要手段。(airborne inertial-SLAM is very important for UAV navigation in unknown environment.)

Huffman code的matlab程序，用一幅图像作为training image得到像素的Huffman编码，然后编码另外一幅图像，求得average code length。(Huffman code of matlab program, with an image as a training image pixel Huffman coding, then coded another image obtained average code length.)

本书提供了matlab语言的编程语法和基本函数，并给出了simulink仿真实例，对于学习matlab的人来说非常有用(This book provides a matlab programming language syntax and basic functions, and gives simulink simulation for learning matlab very useful for people who)
