最佳升余弦滚降系统的多径传输. 滚降系数0.5, 取样时间无偏差.(best Raised Cosine system multipath transmission. Roll-off coefficient of 0.5, sampling time without deviation.)

matlab实现了OFDM功能，ACO-OFDM可以在可见光中使用。(Orthogonal frequency division multiplexing (OFDM) is a modulation technique which is now used in most new and emerging broadband wired and wireless communication systems because it is an effective solution to intersymbol interference caused by a dispersive channel. )

说明：  遗传算法实现的阈值分割图像的代码，内附图片，可直接运行(Genetic algorithm for image segmentation code, containing pictures, can be directly run)

This is a matlab code and is a beneficial source code about filtering

局部最小距离分类器，性能高于knn分类器，matlab环境下，可直接调用(Local minimum distance classifier, classifier performance than knn, matlab environment, can be called directly)

用改进的周期图（Bartlett）法求1KHz方波信号加高斯白噪声的功率谱密度(Use the Bartlett to compute the power spectral density)

说明：  熟悉MATLAB的命令窗口。掌握MATLAB一些基本操作，能进行一般的数值计算。实现语句的重调和修改 。 (Familiar with the MATLAB command window. MATLAB grasp some basic operations, to carry out general numerical calculation. Achieve reconciliation statement heavy modifications.)

说明：  matlab 图像处理，很好，强力推荐，分享(matlab image processing, very good, highly recommended, to share)
