Exponentially weighted covariance matrix

Simulation doppler effect in matlab

有信道编码，调制，信道估计等，包括最小二乘法、SVM、神经网络、1_k近邻法,通过matlab代码。( Channel coding, modulation, channel estimation, Including the least squares method, the SVM, neural networks, 1 _k neighbor method, By matlab code.)

利用差分进化算法（Differential Evolution）实现对经典函数girewangk的验证(The use of differential evolution algorithm (Differential Evolution) to achieve the verification of classical function girewangk)

线性调频信号是典型的脉冲压缩信号，在雷达波形设计中要重要的作用。本实例给出了调频雷达中混入正弦波噪声和高斯噪声时如何抑制噪声从而恢复调频信号的过程(LFM signal is a typical pulse compression signal, the radar waveform design to an important role. This example shows the sine wave frequency modulated radar mixed with noise and Gaussian noise, how to suppress the noise FM signal to the process of recovery)

说明：  卡尔曼滤波器，可以对所得到的数据进行平滑，matlab源码(Kalman filter can be obtained by smoothing the data, matlab source)

单频网的链路级Matlab仿真程序,直接运行可得到误符号率。(Link level simulator for single carrier networks,The simulator outputs symbol error rate.)

文档介绍了matlab工具箱的使用情况。对于初学者是非常有帮助的。(Document describes the use of matlab toolbox. For beginners it is very helpful.)

Matlab提取主分量矩阵。程序设计步骤： 1、去均值 2、计算协方差矩阵及其特征值和特征向量 3、计算协方差矩阵的特征值大于阈值的个数 4、降序排列特征值 5、去掉较小的特征值 6、去掉较大的特征值(一般没有这一步） 7、合并选择的特征值 8、选择相应的特征值和特征向量 9、计算白化矩阵 10、提取主分量()

关联规则挖掘算法的matlab程序，我编写了Apriori算法的FLpMGH 步骤，可以自动生成关联规则，计算支持度、置信度以及 aXlJybd 检测，很好的小程序。(Association rule mining algorithm matlab program, I wrote FLpMGH step Apriori algorithm can automatically generate association rules, computing support, confidence and aXlJybd detection, good little program.)
