经典谱估计方法的MATLAB分析,主要是周期图法及其改进(MATLAB classical analysis of spectral estimation method, the main improvement is the periodogram and)

MATLAB教学代码，包括37个短代码M文件，文字包含执行基本线性代数计算MATLAB命令文件等。(The MATLAB Teaching Codes consist of 37 short, text files containing MATLAB commands for performing basic linear algebra computations.)

说明：  AR经典程序,AR Classic program,ke y ij ing xing pu fen xi.jiao shiyong(AR Classic program,ke y ij ing xing pu fen xi.jiao shiyong.AR Classic program,ke y ij ing xing pu fen xi.jiao shiyong)

说明：  观察数据长度N的变化对DTFT分辨率的影响 这几个程序是老师写的 对于理解DTFT有很大帮助(Effect of observation data length N on DTFT resolution These programs are written by the teacher and are very helpful for understanding DTFT.)

说明：  wsn路由，用matlab仿真，具有选簇的功能(WSN routing, simulated with MATLAB, has the function of cluster selection)

利用matlab计算图像变化前后的信噪比！(Use the matlab to calculate the Signal to Noise Ratio!)

程序是基于贝叶斯最小错误率的分类器的设计，真确率达到98 ，学习模式识别的很好的程序(Program is based on the Bayes minimum error rate classifier design, true rate of 98 , a good learning pattern recognition program)

本程序将时域数据转换为频域（功率谱密度），方便数据的处理和分析。(The program time-domain data is converted to the frequency domain (power spectral density), to facilitate the processing and analysis of data.)

以高斯函数为载波的PPM调制解调，及于理想误码率曲线相比较的误码率曲线(Gaussian function of PPM modulation and demodulation of the carrier, and the desired BER curves compared to BER curves)

these codes are about simulation of vcsel laser diod
