进行了3D MIMO下多用户的系统容量和Taylor容量的对比(Compare the multi-user system capacity in 3D MIMO)

利用小波变换模极大值方法进行信号检测的实验，下面是我在MATLAB中做的程序(Using wavelet transform modulus maxima method of signal detection experiments, the following is what I do in the MATLAB procedure)

说明：  边缘预测提出了一种基于预测的、有一定自适应性的边缘检测方法。介绍了其原理和算法实现过程。通过计算两个相邻像素的灰度值的均值、均方差和梯度来预测下一个像素的灰度值,比较预测值和真实值来判断下一个像素是否是边界点。通过与现有同类算法的比较,证明了该算法的优越性(A predictive and adaptive edge detection method is proposed. The principle and implementation process of the algorithm are introduced. The gray value of the next pixel is predicted by calculating the mean, mean square deviation and gradient of the gray value of the two adjacent pixels. The prediction value and the real value are compared to determine whether the next pixel is a boundary point. The superiority of this algorithm is proved by comparing with the existing similar algorithms.)

说明：  图像反投影重建算法，利用CT采集的数据在进行R_L_滤波后进行反投影得到检测图像。(Image reconstruction algorithm, using the projection of the data collected on CT after R_L_ filter back-projection get detection images.)
