signal-and-system

这里几种功率谱估计方法，对它们的性能进行了比较，可供参考！(Here several methods of power spectrum estimation of their performance are compared for the reference!)

Antenna can also be termed as an Aerial. Plural of it is, antennae or antennas. Now-adays, antennas have undergone many changes, in accordance with their size and shape. There are many types of antennas depending upon their wide variety of applications.

说明：  基于自组织特征映射（SOM）的系统辨识算法实现(Based on self-organizing feature map (SOM) of the system identification algorithm)

西北工业大学研究生课程，数字信号处理上机作业三(Northwestern Polytechnical University post-graduate courses, digital signal processing, machine operating)

对实测获取的风速数据进行处理，评估平均风速和风向。(To deal with measured to obtain the wind speed data, uate the average wind speed and direction.)

FFT加窗分析，计算幅值，相位，可以自己定义信号，加窗后相位差以及插值法(FFT window analysis)

说明：  只需输入车辆图片，即可实现包括车牌检测、车牌定位、车牌字符分割、车牌字符识别的全流程图形化演示，非常形象！拥有完整matlab源代码，是学习模式识别的高贵编程参考。(Just enter the vehicle picture, you can achieve, including license plate detection, license plate location, license plate character segmentation, the whole process of license plate character recognition graphical presentations, very image! Matlab has a complete source code, is to learn the noble pattern recognition programming reference.)

使用matlab进行仿真，还有pca降维，kl变换方法进行人脸识别的参考论文(Using MATLAB simulation, and the PCA dimension reduction, the KL transform method for face recognition reference papers)
