Comparison of BPSK and QPSK modulation

optimization 的经典方法，这是第三个例子，共六个方法在其中。(optimization of the classical method, which is the third example, a total of six ways in which the.)

本程序验证手写fft频谱分析的正确性，并用于信号频域积分和频率检测。包含文档详细解释。(This procedure verified the correctness of handwritten fft spectrum analysis, and for the signal frequency-domain points and frequency of testing. Contains the document explained in detail.)

MATLAB在概率统计中的应用 参数估计 回归分析 (MATLAB application in probability and statistics parameter estimation regression analysis )

对matlab解决图论问题的算法做个汇总。主要包括：顶点覆盖近似算法、哈密尔顿回路、最大流和最小截、最短路和次短路、最小生成树Prim算法、最短路径等等。由于太多就不一一列举了。(Matlab to solve the problem of graph theory algorithms to be aggregated. Include: vertex cover approximation algorithm, Hamilton circuit, the maximum flow and minimum cut shortest times short circuit, Prim minimum spanning tree algorithm, the shortest path. Not because of too many to enumerate.)

附件是人脸检测matlab程序，需要调用dll文件。

数字水印技术是近年来图像保护技术研究领域的一个热点,本文提出了一种基于小波变换的图像数字水印嵌入算法的Matlab实现。实验结果表明,该算法具有较好的视觉效果和透明性。 (Abstract　The digital watermarking technology is the most active topic in image protecting recently.In this paper, a digital watermarking algorithm based on Wavelet transform is proposed,and give ou the program of this algorithm by MatLab.The experimental results demonstrate that the method possess good vision effect and transparence.

Algorithm as described in "CoSaMP: Iterative signal recovery from incomplete and inaccurate samples"

本程序是利用同伦方法求解L1范数最小化的数值算法(This procedure is the use of homotopy methods to solve the L1-norm minimization numerical algorithm)

1《基于最小二乘支持向量机的压力传感器温度补偿》    1）正规化参数C和RBF和函数的参数决定了 LS- SVM的学习能力和函数逼近能力。本文用自适应参数优化 的方法来整定这 2个参数[7 ]。。其优化步骤是先分别确定这 2 个参数的取值范围,然后将这 2个取值范围分别 m和 n等 份,构成 m × n对参数,再将生成的参数对应用于 LS2 S VM学 习,取最小学习误差对应的参数对为最优参数。如果误差精度达 不到要求,则以当前最优参数对为中心缩小取值范围重 复以上步骤,继续优化参数,直至达到所要求的误差精度。
