包括完整的Turbo码编码和译码程序，可用于实验仿真和教学。主文件为一个测试文件，仅对一个Turbo码字进行译码。(The uploaded matlab files including the Turbo code encoding and decoding programs can be used for simulations and teaching. The main file is a test file, which only decodes one Turbo codeword.)

已知一个序列x(n)=0.5cos(0.55*pi*n)+cos(0.45*pi*n),时域FFT分析其频谱。 （1）使用不同宽度的矩形窗截断该序列为M点，取M分别为：20，40，160,观察不同长度对频谱影响；（2）使用哈明窗和凯泽窗重做；（3）对三种窗的结果进行分析比较；（4）总结窗类型和长度对频谱分析的影响。 (Known a sequence x (n) = 0.5cos (0.55* pi* n)+ Cos (0.45* pi* n), time-domain FFT analysis of its spectrum. (1) use a different width of the rectangular window of the sequence for M cut-off point, take M are as follows: 20,40,160, observing the impact of different lengths of the spectrum (2) the use of Hamming window and the Kaiser window redo (3 ) on the three windows analyzed and compared the results (4) summarize the type and length of window for spectrum analysis.)

本课件主要讲述MMatlab Simulink中S函数(Function)的写法,其中包含非常实用的S-函数介绍（为什么要引入S-Function？)、S-函数的分类、使用（实例演习）等(The courseware in the main about MMatlab Simulink S function (Function) is written, which contains the S-function is very useful Introduction (why the introduction of S-Function?), S-function category, the use of (example exercises), etc.)
