preprocessing ECG signal with matlab

很好的matlab 的显示程序啊 欢迎下载啊(Very good display procedures matlab download ah ah welcome)

说明：  不同信噪比下ofdm系统的仿真程序，不同的误码率(OFDM systems under different signal to noise ratio of the simulation program, different BER)

matlab 灰度图像处理去噪 可以有效改变图像的边缘化问题(matlab grey processing )

如下亮度变换功能的函数：负片变换、对数变换、gamma变换、和对比度拉伸变换。(Brightness as a function of conversion functions: negative transformation, logarithmic transformation, gamma conversion, and contrast stretching transformation.)

说明：  自适应滤波器。自适应滤波器为11个权系数的FIR结构。（1）不同的方差σ2（2）LMS算法画出一次实验的误差平方收敛曲线，训练长度为500，给出滤波器系数；进行20次独立实验，给出平均收敛曲线。不同步长值的比较。（3）RLS算法，LMS和RLS算法的比较 (Adaptive filter. Adaptive filter weights for 11 of the FIR structure. (1) different variance σ2 (2) LMS algorithm for an experiment to draw square error convergence curve, the training length is 500, given filter coefficient conduct 20 independent experiments, given the average convergence curve. Are not synchronized long value comparison. (3) RLS algorithm, LMS and RLS Algorithms)

基于粒子群优化最小二乘支持向量机参数的程序，很好用！！！(pos_lssvm)

一个有关图像分割算法的Matlab源程序 (Image segmentation algorithm Matlab source code)

该程序完成一个16电平PAM数字通信系统的仿真，并测量了它的误码率。首先产生信息符号序列，该序列被当做4个信息比特一组，将16组符号映射到16个信息幅度。检测器计算距离，输出与真正传输的信息符号序列作比较，然后将差错计数。( This procedure completes a 16 level PAM digital communication system s simulation, and has surveyed its error rate. First has the message digit sequence, this sequence is treated as a 4 information bit group, maps 16 class symbols to 16 information scopes. The detector estimated range, the output and the true transmission s message digit sequence does compares, then counts the mistake. )

说明：  多线性主成分分析的MATLAB源代码 最初用于人脸识别和步态识别 后被扩展到其他应用领域(The codes implement two algorithms: Multilinear Principal Component Analysis (MPCA) and MPCA+LDA.)
