快速傅里叶变换 (FFT) 实现，给定信号x(t)=sin(2πf0t)，f0=50Hz，对x(t)以fs=200Hz进行抽样，抽样点数为N=16。编写程序实现对x(n)的快速傅里叶变换，求得相应的X(K)。(Fast Fourier Transform (FFT) to achieve a given signal x (t) = sin (2πf0t), f0 = 50Hz, for x (t) with fs = 200Hz sampling, the sampling points is N = 16. Procedures for the preparation of x (n) of the fast Fourier transform, obtained by the corresponding X (K).)

Unmanned based Wireless WSN

In order to start using GNSS-SDR, you may want to populate ```gnss-sdr/data``` folder (or anywhere else on your system) with raw data files. By raw data we mean the output of a Radio Frequency front-end s Analog-to-Digital converter. GNSS-SDR needs signal samples already in baseband or in passband, at a suitable intemediate frequency (on the order of MHz). Prepare your configuration file, and then you are ready for running ```gnss-sdr config_file=your_configuration.conf```, and seeing how the file is processed.

此程序计算了会聚偏振光的干涉图样，其结果对于偏振光的分析有指导作用。(This program calculated convergent polarized light interference pattern, the results of the analysis for the polarized light guide.)

说明：  简单遗传算法MATLAB实现，详细的介绍了简单遗传算法的实现过程，并以一个简单的函数优化作为案例说明了其应用。但是由于该测试函数过于简单，在实际的应用过程中，还需要对相关参数进行调整，使其效率得到更大的提高。(Simple genetic algorithm based on MATLAB realize, describes in detail the process of simple genetic algorithm, and a simple function optimization as a case illustrate its application. However, since the test function is too simple, in the actual application process, the relevant parameters need to be adjusted to greater increase efficiency.)
