现代信号检测与方法，主要分析正交频分复用信号检测与调制识别(signal detection)

性能最好的单用户能量检测频谱感知，都是最好的东西，曲线和理论值进行比较，效果明显。欢迎批评指正。(The best performance of a single-user energy detection spectrum sensing, are the best thing, curves and theoretical values ​ ​ are compared, the effect is obvious. Welcome criticism.)

this is a project for voice recognition in matlab using vector quantization.

支持向量机SVM和核函数的MATLAB程序集,用于图形处理的算法，分类算法(pca and svm use MATLAB )

详细介绍matlab基础及应用的教学课件，课件共分13章进行讲解：matlab操作基础，矩阵及其运算，程序设计，文件操作，绘图，数据分析与多项式计算，解方程与函数极值，数值积分与微分，符号计算，图形句柄，图形用户界面设计，Simulink动态仿真集成环境，在Word环境下使用MATLAB。可用于matlab自学(Details matlab basic and applied courseware, courseware is divided into 13 chapters explain: matlab operation based on the matrix and its operation, the program design, file operations, graphics, data analysis, and polynomial calculation, solving equations with function extremum numerical integration and differentiation, symbolic computation, the graphics handle graphical user interface design, Simulink dynamic simulation integrated environment, in Word using the MATLAB environment. )

用双线性法设计巴特沃斯低通滤波器，并用正弦信号验证。(Bilinear design Butterworth low-pass filter with a sinusoidal signal verification.)

特征值分解的例子，music算法，pisarenko算法等(Eigenvalue decomposition of the example, music algorithm, pisarenko algorithm)
