Euler-maruyama 方法生成色噪声(Euler-maruyama method to generate colored noise)

rd算法关于三个点目标雷达成像，对初学者有用。(rd algorithm on the three point target radar imaging, be useful for beginners.)

用于求解matlab排序问题，求解得效率很高，比一般的方法好哦(Matlab for solving the scheduling problem, to solve a highly efficient method than the average好哦)

用自适应法做时延估计，然后根据时延估计确定声源的定位(Adaptive time delay estimation method used to do, and then determine the time delay estimation based on the positioning of the sound source)

MIMO传输信道仿真 对信道进行编码、解码(MIMO transmission channel simulation of channel coding and decoding)

说明：  通过设计GUI界面，实现图像的读取、保存、灰度变化、直方图、多种增强、滤波，图像复原、多种边缘检测、图像放大、缩小等 (Through the design of GUI interfaces to achieve the image to read, save, gray change, histogram, a variety of enhancement, filtering, image restoration, multi-edge detection, image scaling,)

matlab实现的FGLG算法，效果较好，可以直接使用，也可以参考学习(FGLG algorithm matlab implementation, better, can be used directly, or you can refer to learning)

这是我在学matlab时的一个例子，我感觉是入门的一个导师。(This is my students an example of when matlab, I feel is the entry of a mentor.)

一个OFDM符号128个有效符号，插入128个虚拟子载波 符号率（即有效数据率）fsymbol，而发送速率（需要包括虚拟子载波）2fsymbol 输入的数据需要2倍的发送数据率，以便进行内插，实现位定时跟踪，即4倍fsymbol采样率的调制信号 OFDM symbol Nfft=128 points 一个OFDM符号数据点 Nfft*2 = 256 ， Guard Interval点 ＝Ng*2=64 ( a OFDM symbol 128 effective symbols, insert 128 virtual sub-carrier symbol rate (i.e. valid data rate), and fsymbol sending rate (need to include virtual sub-carrier) 2fsymbol input data need 2 times the sending data rate for interpolation, realize a timing tracking, namely fsymbol sampling rates four times the modulation signal OFDM symbol Nfft = 128 points a OFDM symbol of data points Nfft* 2 = 256, Guard Interval point = Ng* 2 = 64 )
