Simulation of QAM + AWGN + Rayleigh Fading(Simulation of QAM+ AWGN+ Rayleigh Fading)

pso算法，这个算法对初学者比较适合~~(pso For beginners are better adapted )

短时傅里叶变换可以用差分模式来实现，对书上的运算式做了稍许的改变。改变-计算差分序列的第一列数据时用的是第一列的元素减去当前行的最后一列元素。原算法中采用的是第一列元素减去下一行第二列元素。原算法加窗之后结果比较好，不加窗时结果误差很大，而改变之后的算法不加窗效果依然很好。(Short time Fourier transform can be used to achieve the differential mode of expression on the book made a slight change. Change- calculating the difference sequence of the data with the first column is the first column of the matrix by subtracting the current element in the last column of row. Is used in the original algorithm subtracts the elements of the first column of the next row and the second column elements. After the results of the original algorithm windowed better, when the results window without great error, and after changing algorithms no window effect is still very good.)

实现MSK数字通信系统仿真。通信信道模型中的噪声为理想加性高斯噪声。接收端有自适应滤波器。(Simulate MSK communication system. Noise in communication channel is additive Gaussian noise. Adaptive filter is designed at receiving terminal.)

通用的牛顿拉夫逊法潮流计算程序，可以自行输入支路参数矩阵，节点参数矩阵。(Universal Newton Raphson power flow )

说明：  matlab下进行图像超精度重构，在频域中计算图像间的相互位移，然后再重构(matlab under the ultra-precision image reconstruction, in the frequency domain calculation of the mutual displacement between images, and then remodeling)

本仿真将延迟-相加法和CAPON算法做对比，分析了其分辨率的能力强弱(The simulation will be delayed- the sum method and the CAPON algorithm to do comparison, analysis of strengths and weaknesses of its resolution)
