基于峭度的快速固定点算法的Matlab实现(a code to realize FastICA)

线性递减权重粒子群优化算法是从随机解出发，通过迭代寻找最优解，它也是通过适应度来评价解的品质，但它比遗传算法规则更为简单，它没有遗传算法的“交叉”(Crossover) 和“变异”(Mutation) 操作，它通过追随当前搜索到的最优值来寻找全局最优。这种算法以其实现容易、精度高、收敛快等优点引起了学术界的重视，并且在解决实际问题中展示了其优越性。 (Linear decreasing weight particle swarm optimization starting from random solutions to find the optimal solution by iteration, it is also the fitness to evaluate the quality of the solution, but it is much simpler than the genetic algorithm rules, it is not a genetic algorithm " cross" (Crossover) and " variation" (Mutation) operation, which follow the current search for the optimal value to find the global optimum. The advantage of this algorithm is its ease of implementation, high accuracy, fast convergence and attracted the attention of the academic community, and demonstrated its superiority in solving practical problems.)

附件里面是三相光伏模型，pq控制，大家共享(Three phase photovoltaic model, PQ control, we share)

通信系统中常用的多进制数字相位调制的源代码 并结合ofdm系统 加入了相应的保护前缀（cp）和导频序列 应用于有关ofdm的信道估计等系统(Communication systems commonly used in multi-band digital phase modulation of the source code and combine OFDM system by adding a prefix corresponding protection (cp) and the pilot sequence used in the relevant channel estimation of OFDM systems)

说明：   采用一种不完全的微分算法，被控对象为时滞系统。对象的输出端加的随机信号，幅值0.01.采样时间是20ms。(PID Controler with Partial differential)

GO-CFAR检测是信号处理中非常常用的检测方法。该程序比较了理论值和实际值的仿真结果。实际中雷达信号往往是起伏的，该程序从SweringI型为例。(GO-CFAR detection is very commonly used detection methods in signal processing. The program compares the simulation results of the theoretical and actual values. The actual radar signals often are ups and downs of the program from SweringI type, for example.)

这是本人编写的PLS建模程序，希望对大家关于该方面的研究有帮助。(This is my procedure to prepare the PLS modeling, I hope all of you on the research helpful.)

说明：  视频图像的采集，捕捉的小程序，在MATLAB环境下运行，有预览、捕捉图像、连续捕捉等功能。(Video image capture, capture a small program to run in the MATLAB environment, there is preview, capture images, continuous capture functions.)

试过很多matlab机器人工具箱，这个是好用的，带使用说明书和例子。(Tried of many-matlab robots Toolbox, this is easy to use, with manual and examples.)
