Matlab的数理统计工具箱是Matlab工具箱中较为简单的一个，其牵扯的数学知识是大家都很熟悉的数理统计，因此在本文中，我们将不再对数理统计的知识进行重复，仅仅列出数理统计工具箱的一些函数，这些函数的意义都很明确，使用也很简单，为了进一步简明，本文也仅仅给出了函数的名称，没有列出函数的参数以及使用方法，大家只需简单的在Matlab工作空间中输入“help 函数名”，便可以得到这些函数详细的使用方法。(Mathematical Statistics Toolbox Matlab Matlab toolbox is a relatively simple one, it involves mathematical knowledge is the number of people are familiar with statistics, so in this article, we will no longer be on the knowledge of mathematical statistics to repeat, only lists Mathematical Statistics Toolbox functions that the meaning of these functions are very clear, very simple to use, in order to further condensed, this article only gives the name of the function, the parameters of the function is not listed, and the use of methods, we simply Enter the workspace in the Matlab " help function name" , it can be to use these functions in detail.)

实上，我们可以把系统框图中外编码器、交织器和内编码器三部分级联后的总体，看作一个级联码的编码器，同理，外译码器、去交织器和内译码器三部分级联后的总体构成了级联码的译码器。 本次仿真外编码采用（7，4）HAMMING码，内编码采用（2，1，3）卷积码。交织编码采用（7，4）卷积交织编码或循环等差交织编码。除特别说明外，交织编码采用前者即（7，4）卷积交织编码。 (failed to translate)

把微分方程的一维经典初值问题的有限插分法：Euler法、改进的Euler法、Admas二步外插法、Admas二步内插法编写成通用子程序，并且利用这些通用子程序解决常微分方程的数值解。(The classical one-dimensional differential equations initial value problem of limited interpolation method: Euler method, improved Euler method, Admas outside the two-step interpolation, Admas two-step interpolation method into a general-purpose subroutine to prepare and use it to solve common subroutines Numerical Solution of Ordinary Differential Equations.)

说明：  观察高斯序列 的时域和幅频特性。 ①固定p=8，q分别等于2、4、8，观察它们的时域和幅频特性，了解当q取不同值时，对信号序列的时域和幅频特性的影响 ②固定q=8，p分别等于8、13、14，观察p变化对信号序列时域和幅频特性的影响，注意p等于多少时，会发生明显的泄露现象，混叠是否也随之出现？记录实验中观察到得现象，绘出相应的时域序列和幅频特性曲线(Observed Gaussian sequence in time domain and amplitude-frequency characteristics. ① fixed p = 8, q is equal to 2,4,8 respectively, to observe them in time domain and amplitude-frequency characteristics, to understand when the different values of q, the signal sequence in time domain and amplitude-frequency characteristics of ② fixed q = 8 , p is equal to 8,13,14 respectively, to observe the changes in the signal sequence p in time domain and amplitude-frequency characteristics, note that p is equal to the number when the apparent leakage phenomenon, aliasing is also gone? Records of the experiment was observed phenomenon, draw the corresponding time-domain sequence and amplitude-frequency characteristic curves)
