做信号处理的时候经常会用到FFT，而MATLAB自带的FFT只能变换出一列系数，想做成频谱图还要自己加一部分，自己写了一个小程序，输入原始信号和采样率，可以画出标准的幅值谱和功率谱。(Do signal processing is often used when the FFT, and FFT MATLAB own transformation from a coefficient of only wanted to make Canada part of the spectrum but also their own, to write a small program, the input original signal and the sampling rate can be Draw a standard amplitude spectrum and power spectrum.)

说明：  求解定义区间内的函数值，求解定义区间内的函数值，求解定义区间内的函数值(Solving the function value defined intervals)

说明：  将标准微粒群算法进行改进，从而解决标准PSO算法的容易陷入局部最优解的情况。(The standard particle swarm algorithm is improved so as to solve the standard PSO algorithm is easy to fall into local optimal solution of the situation.)

MATLAB编程实现拟牛顿法（BFGS），对凸函数进行优化计算(The quasi-Newton method (BFGS) is realized by programming in MATLAB, and the convex function is optimized.)

this code have the solution of a neural network book.

(书)现代通信系统使用MATLAB第四章(ALLIANCES is a recently proposed cooperative random access protocol for wireless networks. In this paper we modify the original model to include user location information. We also derive pair-wise error probability (PEP) under Rayleigh flat fading channel and a power-law attenuation environment. Based on the PEP analysis we propose an optimal relay selection scheme, which achieves significant throughput gains as compared to the random relay selection scheme in the original ALLIANCES.)

说明：  这是一篇关于4G方面的一篇文章，它主要是介绍了4G的一些关键技术，如智能天线技术、MIMO技术、中继技术等。

说明：  matlab仿真估计多普勒中心频率，通过图像偏移法，(estimation of doppler center)

The following Matlab project contains the source code and Matlab examples used for 16 bits fixed point pid controller . This simulation illustrates the effects of the fixed-point computations on the closed-loop precision for a 16-bits PID controller. The source code and files included in this project are listed in the project files section, please make sure whether the listed source code meet your needs there.
