分析相位耦合的两个算例，分别利用了双谱和双相干系数法(Analysis of phase coupling of two examples, namely the use of a dual spectrum and bicoherence France)

X信号的时域和频域分析，及针对该信号的滤波器设计、验证(X signals in time domain and frequency domain analysis, and for the signal of the filter design, verification)

图像分块的很好的算法，大家可以参考一下，希望对大家有帮助(Image segmentation algorithm, we can refer to the help)

contrast adjusment Contrast is the difference in luminance or color that makes an object (or its representation in an image or display) distinguishable. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view. Because the human visual system is more sensitive to contrast than absolute luminance, we can perceive the world similarly regardless of the huge changes in illumination over the day or place to place. The maximum contrast of an image is the contrast ratio or dynamic range

This program plots sensitivity of OFDM subcarriers with Carrier frequency offset(CFO)

使用MATLAB编写的qdudqz神经网络算法，本程序根据训练好的网络文件DNViuWY预测新的数据文件，得到算法的最差性能和最优性能，并绘制出预测数据和原数据的对比图。调试运行正常。 (Using MATLAB preparedqdudqz neural network algorithm, the program according to the trained network fileDNViuWY anticipating new data files to obtain the best performance and the worst performance of the algorithm, and draw out the comparison chart data and predict the original data. Debugging and running properly. )

说明：  偏最小二乘法的原始程序，粒子群优化算法对支持向量机SVM的优化。对初学者有帮助。套用模型，可以改PSO-SVR。(Partial least squares method of the original program, particle swarm optimization algorithm for support vector machine SVM optimization. It is helpful for beginners. Applying the model, PSO-SVR can be changed.)
