本代码在MATLAB中采用均方误差和测度两种评价参数对维纳滤波和L-R算法复原的加入噪声的运动模型和高斯模型的图像复原效果进行了比较-The code in MATLAB using the mean square error and two evaluation parameters measure the effect of exercise on the model image restoration Wiener filtering and restoration LR algorith

对离散点进行圆拟合，得到拟合圆的中心坐标和半径- [Z, R] = FITCIRCLE(X) fits a circle to the N points in X minimising geometric error (sum of squared distances the points to the fitted circle) using nonlinear least squares (Gauss Newton)

（可用）协同通信的DF（解码转发）基本性能，基本模型S-R-D三个节点，接收端使用MRC（最大比合并）。固定DF由于SR信道的错误，其性能受到限制，在大SNR情况下不能获得有效分集。而当SR距离足够近的时候，可能获得一定的分集增益-(Available) co-communication DF (decode forwarding) basic performance, the basic model S-R-D three nodes, the receiver uses MRC (maxim
