说明：  利用pid控制永磁同步电机，永磁同步电机的PID控制(PID control of permanent magnet synchronous motor using PID control of permanent magnet synchronous motor)

针对二维矩形条带装箱问题提出了一种启发式布局算法，即底部左齐择优匹配算法（lowest—level left align bestfit，简称LLABF）．LLABF算法遵循最佳匹配优先原则，该原则综合考虑完全匹配优先、宽度匹配优先、高度匹配优先、组合宽度匹配优先及可装入优先等启发式规则．与BL（bottom-left），IBL（improved-bottom-left）与BLF（bottom—left-fill）等启发算法不同的是，LLABF能够在矩形装入过程中自动选择与可装区域匹配的下一个待装矩形．计算结果表明，LLABF结合遗传算法（genetie algorithm,简称GA）解决二维条带装箱问题更加有效．(A heuristic placement algorithm for two-dimensional rectangular strip packing problem is proposed, which is called bottom-level left align best fit algorithm (LLABF). Different from BL (bottom-left), IBL (improved-bottom-left) and BLF (bottom-left-fill) heuristic algorithms, LLABF can automatically select the next rectangle to be loaded that matches the mountable region during the rectangular loading process. Genetie algorithm (GA) is more effective to solve the two-dimensional strip packing problem.)

用于分数倍时延调整的farrow滤波器仿真。其中使用了4阶，8阶和16阶farrow滤波器。m文件为滤波器系数产生函数，mdl文件为滤波后偏差估计的情况。(Adjustment for fractional delay filter simulation farrow. Which uses the four bands, 8 bands and 16 bands farrow filter. m file for the filter coefficients of the production function, mdl file for the deviation of the filtered estimate of the situation.)

这是我们通信建模与仿真书上的程序，是白噪声＆瑞利信道下对OFDM的仿真实现。(This is our communication on Modeling and Simulation on the procedures, White Noise & Rayleigh Channel on OFDM Simulation.)

可以有效方便地对原始数据进行自适应分解，广泛用于故障诊断和模式识别等方面的特征提取。(Can be effectively and easily decompose the raw data adaptively, widely used in troubleshooting and other aspects of the pattern recognition feature extraction.)

线性方程组的直接发的源代码，matlab编写的，值得收藏，欢迎大家踊跃下载，为中国的科研事业做贡献(Linear equations of the source code directly, matlab prepared and worthy of collection, enthusiastically welcomed the U.S. download, in order to make China' s contribution to the cause of scientific research)

说明：  sphereandML是主程序，性能接近最大似然ML检测，调用了spheredecode和spheredecodeinf两个子程序；(ml sd )

这是我自己写的knn的算法，实现了聚类，比较简单(This is what I wrote it myself knn algorithm implements clustering, relatively simple)

说明：  MATLAB噪声模型计算。半导体器件设计用。(MATLAB noise model. Semiconductor device design.)
