《无线通信与原理应用》中QPSK编码的误码率曲线绘制的代码，简洁易懂。有注释，方便修改。("Wireless communications and Principle" in the QPSK coded BER curve drawing code, concise and easy to understand. Notes, easy to modify.)

采样时间：1E-6秒 脉冲长度：200E-6秒（脉冲宽度=200个样本） 脉冲间隔：1E-3秒（脉冲周期=1000个样本） 初始频率啁啾：DC至200 kHz（目标频率） 扫描时间：200E-6（200个样本） (Sample Time: 1e-6 sec Pulse Length: 200e-6 sec (Pulse width=200 samples) Pulse Interval: 1e-3 sec (Pulse period=1000 samples) Chirp: DC (initial freq) to 200 kHz (target freq) Sweep time: 200e-6 (200 samples))

一个关于金属细导线的matlab程序。程序计算了偶极子的远场，方向图，增益等参量(A thin metal wire on the matlab program. Are calculated dipole far-field, pattern, gain and other parameters)

神经网络的ELM算法，比传统的BP和SVM都快，而且效果也很精确。运行平台是matlab，本人已经对原始ELM做了修改，可以适应多种函数，而且在数据处理方面自动产生分类矩阵。(ELM neural network algorithm, than the traditional BP and SVM faster, but the effect is also very accurate. Platform is running matlab, I have to do the original ELM been modified to adapt to a variety of functions, but also in data processing is automatically generated classification matrix.)

一幅彩色图像数字化后，在显示时颜色经常看起来有些不正常。这是色通道的不同敏感度，增光因子和偏移量造成的，称为三基色不平衡。这个校正过程称为彩色平衡。(After a digital color image in the display color always looks somewhat normal. This is a different color channel sensitivity factor and credit to offset caused by the imbalance as the three primary colors. This correction process is called color balance.)

This code computes the distance and azimuth an earthquake to a station. It is necessary to provide the latitude and longitude bothe for the earthquake and the station.

基于极性LMS算法的对于多信号波达角方向估计，基于32单元线阵(LMS algorithm based on the polarity of the multi-signal angle of arrival direction is estimated, based on the 32-cell linear array)

说明：  该文件包含了一般的FCM聚类算法和改进的FCM聚类算法(The document contains a general FCM clustering algorithm and the improved FCM clustering algorithm)

该函数为OMP算法的函数实现，可以直接来调用，其根据沙维老师的CS_OMP改编(This function is a function of OMP algorithm to achieve, you can call directly to their teacher s CS_OMP adapted according to Shawei)

同配系数，是复杂网络中计算度与度之间的关系的重要参量。大于0表示，网络是同配的。(With the distribution coefficient, is a complex calculation of network reliability and degree of the relationship between the important parameters. Greater than 0, said network is the same allocation.)
