亲测可用的现代信号处理中谱估计应用程序

for graphing quadratic functions

提取点云的边缘，最小二乘法拟合曲面的方法 效果特别好(To extract the edge of the point cloud, the least squares fitting method of surface effect is very good)

采用小波提取布料图像的纹理，提取出经纬纱的纹理，效果还好。演示用吧(using wavelet to extract Woven Fabrics feature, it alse can automatic analysis techniques to identify the fabric density)

很少见的六角阵波束形成的相关仿真及其相关的各种图形(Rare hexagonal array beamformed related simulation and its associated various graphics)

基于BP神经网络的图形图像压缩算法 可以运行(BP neural network can run a graphical image compression algorithm based on)

说明：  经典又好用的时间序列模型ARIMA，某些场合比GA还要好用的(ARIMA, a classic and useful time series model, is better than GA in some cases)

1.原始信号A，通过信道受噪声污染后的信号q，然后分别经过均衡器ZF（MMSE）得到信号U，可以画出U的分布图 2.分别应用LMS,SATO,CMA算法得到U。（其中包括最佳延迟、均方误差的计算）所有结果均以图像形式显示。(1. The original signal A, subject to noise pollution through the channel after the signal q, and then through the equalizer, respectively ZF (MMSE) receive the signal U, the distribution of U can draw Figure 2. Were applied LMS, SATO, CMA algorithm to be U. (Including the best delay, mean square error terms) all the results are displayed in graphic form.)
