模拟2个独立窄带信号入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵列的阵元数为10，快拍数为200。阵元间距为入射信号波长的1／2，信噪比为20dB，信号入射角度差分别为5°，10°，20°。(Simulate two independent narrowband signals incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the number of array elements of the array is 10, the number of snapshots to 200. Element spacing is 1/2 of the wavelength of the incident signal, SNR is 20dB, the signal difference between the angle of incidence was 5 °, 10 °, 20 °.)

NONLINEAR LOAD DEMONSTRATION FOR LABORATORY TYPE RECTIFIER

kohonen网络Matlab实现案例，内含具体语句说明，十分详细。 该案例 的准确率在70 左右(ANN(Kohoen))

说明：  数字信号处理中，分别用重叠相加法和重叠保留法求两个序列的线性卷积，并对两种方法的结果进行比较。两种方法的结果是相同的。(Digital signal processing, respectively, and overlap with the overlap-add method to retain Method linear convolution of two sequences, and the two methods were compared. Two results are the same.)

通过计算和作图，比较4PSK和QPSK这两种不同的编码方式之间的优略，说明发射信号一个是三值的一个是二值的(By calculating and plotting, preferably QPSK, and compare these two 4PSK encoding between different strategies, a description of the transmission signal is a ternary value is two)
