This package is a free collection of Matlab routines for computing wave atom transforms in one, two and three dimensions.

基于MATLAB中的M文件实现QPSK及QDPSK的调制，希望能帮助你学习(M-file MATLAB-based implementation of QPSK modulation and QDPSK)

GM11灰色预测模型，通过生成数据的gm(1,1)模型所得到的预测值的逆处理结果(Grey Forecasting)

本段代码实现了手动选点的matlab配准，在此代码中只选择了3对控制点，同时从结果可以看出手动选点配准的不精确性，为自动选点配准算法的提出提供了实验依据(This code implements manually selected point matlab registration, in this code to select only the three pairs of control points, and the results can be seen from the point of registration manually selected imprecision, with the choice of site for the proposed automatic registration algorithm provide an experimental basis)

对雷达多脉冲回波进行匹配滤波处理后，再进行相参积累，提高检测信噪比(Coherent matched filter radar multi-pulse echo, to improve the detection signal to noise ratio)

we use the normalized LMS (NLMS) ,LMS,VSLMS,VSNLMS for the main filter in AEC

Fisherface方法的实现是在PCA数据重构的基础上完成的，首先利用PCA将高维数据投影到低维特征脸子空间，然后再在这个低维特征脸子空间上用LDA特征提取方法得到Fisherface。程序中使用参数寻优的方法来寻找最佳投影维数，以达到比较理想的识别效果。 (The Fisherface method implemented in the PCA data reconstruction based on the completion of the first use of PCA projection of high-dimensional data to a low dimensional feature subspace, and then on the characteristics of low-dimensional subspace LDA feature extraction methods to get the Fisherface. Program parameter optimization method is used to find the best projection dimension, in order to achieve the ideal identification.)

双线性变换的特点是不产生频率混叠失真，是一种很好的设计方法(Bilinear transform the feature is not to produce the frequency aliasing distortion is a good design method)
