Exam4_1

说明：  样本的互相关函数与互协方差的估计值计算 (samples of the cross-correlation function and covariance among the estimated value)

重装系统后恢复matlab文件关联,重装系统后，若没动MATLAB安装目标，则MATLAB不用重新安装。（同样的原因，可以移动MATLAB安装目标）对MATLAB相关文件，建立重新关联就行了。(Reinstall the system restore matlab file association, reinstall the system, if no action MATLAB installation target, MATLAB without having to reinstall. (For the same reason, you can move MATLAB installation target) on MATLAB related files, to establish re-associate on the line.)

QPSK调制与解调，低通滤波器采用了时域和频域两种实现方式，截止频率fc = 200hz,采样频率fs= 1000hz,欢迎下载参考！(QPSK modulation and demodulation, using a low-pass filter with a time domain and frequency domain implemented way, the cutoff frequency fc = 200hz, the sampling frequency fs = 1000hz.Welcome to download !)

Theorical algorithm of RRA or R/S

此程序对协作通信的中继选择和功率控制，采用了蚁群算法。(The program of collaborative communication relay selection and power control, using the ant colony algorithm.)

能够计算出一个图像矩阵的灰度梯度共生矩阵，并计算出其协方差(To calculate an image matrix of gray gradient co-occurrence matrix, and calculate the covariance)
