Matlab QPSK, testing QPKS code

数学建模matlab回归程序 用于解决回归分析中的算法(Mathematical modeling matlab regression procedures for regression analysis to solve the algorithm)

说明：  这是MATLAB和VC相互调用的例子，通过MATCOM来实现，所以想学习如果在VC中调用MATLAB函数的，可以学习一下(This is the MATLAB and examples of VC call each other by MATCOM to achieve, so if you want to learn to call MATLAB functions VC, you can learn about)

channel estimation of communication system for long term evolution

说明：  已知三个信号 ，经调制产生信号 ，其中 为常数， 为具有窄带特性的Hanning信号。将此已调信号通过信道传输，描述该信道的差分方程为 得到接收信号 1）分析Hanning信号 的时域与频域特性 2）分析已调信号 的时域与频域特性 3）分析系统的单位脉冲响应 4）分析接收信号 的频谱 (Three known signal, the modulated signal is generated, which is a constant for the Hanning signal having a narrowband characteristics. This modulated signal channels transmitted through the differential equation of the channel 2) units of analysis of the modulated signal and frequency domain characteristics 3) analysis system is described for obtaining a reception signal 1) Analysis of time domain and frequency domain characteristics Hanning signal 4 impulse response) spectral analysis of the received signal)

matlab遗传算法源码(Matlab genetic algorithm source code)

说明：  提出了一种新的基于离散小波变换(DWT)与奇异值分解(SVD)相结合的数字图像水印算法。该算法将原始图像作小波分解并将小波分解得到的低频子带进行分块，对每一块进行奇异值分解后，选取每块中最大的奇异值通过量化的方法嵌入经过Arnold置乱后水印信息。(A new wavelet transform based on discrete (DWT) and Singular Value Decomposition (SVD) combination of digital image watermarking algorithm. The algorithm for wavelet decomposition of the original image and wavelet decomposition low-frequency sub-band are divided into blocks, each a singular value decomposition, the selection of each block by the largest singular value methods to quantify Arnold scrambled after embedding the watermark .)
