匹配追踪和正交匹配追踪，通过虚拟阵元进行DOA估计，针对EMD方法的不足,实现典型相关分析，GSM中GMSK调制信号的产生。(Matching Pursuit and orthogonal matching pursuit, Conducted through virtual array DOA estimation, For lack of EMD, Achieve canonical correlation analysis, GSM is GMSK modulation signal generation.)

说明：  function result = apm(results1,results2) %

说明：  基于BP神经网络 对虫害进行预测 程序完整(Based on BP neural network to forecast pest program integrity)

说明：  陀螺运动的仿真程序，动力学仿真和动画同时表示 陀螺在重力下以适当的初始速度落地的仿真结果(Gyro movement simulation program, dynamic simulation and animation at the same time that the top of the gravity of the initial velocity to the appropriate landing simulation results)

说明：  通信大牛李叶关于ofdm信道估计的经典论文，研究此方向必看(Daniel Lee leaves on the communication channel estimation ofdm classic paper, research in this direction must see)

Simple but effective example of "Region Growing" from a single seed point. The region is iteratively grown by comparing all unallocated neighbouring pixels to the region. The difference between a pixel s intensity value and the region s mean, is used as a measure of similarity. The pixel with the smallest difference measured this way is allocated to the region. This process stops when the intensity difference between region mean and new pixel becomes larger than a certain treshold

16QAM matlab source coding

说明：  此源码进行图片灰度值的处理，使图片更清晰，或者让其变成纯黑纯白(this code does the image gray level enhancement)

微带天线在已知谐振频率下的结构尺寸计算，以及其3D辐射方向图的展示，还有E面H面的辐射图展示。学习微带天线的同学可以参考~(Size of the microstrip antenna in the calculation of the known resonance frequency, radiation pattern, and its 3D display, and H-plane radiation pattern in E-plane display. Students can learn microstrip antenna reference ~)
