快速傅里叶变换，很实用的！！希望能帮助你(Fast Fourier transform, it is useful! ! Hope you can help)

A guide to matlab for beginner

This code basically computes the BER of an OFDM system. The ifft size is 64. 16QAM is the modulation Technique and convolution encoding rate 1/2 is used as the coding scheme.

Contains a common array signal processing algorithm, Mainly for data analysis and statistics, Using high-order cumulants of MPSK signal modulation recognition.

针对多目标测控问题，提出了一种实用的利用基于圆阵的数字波束形成技术来实现目标跟踪的系统。在系统实际工作于噪声和干扰环境中时，为避免计算梯度时可能出现的数值突变，提出了一种修正的梯度跟踪自适应算法，可靠地实现了权值更新，并对各阵元输出进行加权合并，以获得最大信号输出，同时实现对目标方位角和俯仰角的自动捕获和跟踪，且跟踪迅速、正确、稳定。仿真结果表明了所提出的方案的正确性。(Monitoring and control for multi-objective problem, a practical circular array-based digital beam forming technology to achieve target tracking system. Practical work in the system noise and interference in the environment is investigated in order to avoid calculate the gradient values may be mutations present a modified gradient tracking adaptive algorithms, reliably achieve the right value update, and the output of the array weighted combined to obtain maximum signal output, while achieving the target azimuth and elevation of the automatic capture and tracking, and tracking fast, accurate and stable. Simulation results show that the proposed scheme is correct.)

说明：  另外一个模糊pid控制器matlab程序，没有用到simulink，但也很实用，希望对大家有所帮助！(good)

数字图像中心点的确定、定位、图像的裁剪、以及数字图像样本的输出等。(To determine the center of the digital image, positioning, image cropping, digital image sample output.)
