fft_learn

OFDM等一系列代码分享，包括调制，预编码，信道编码，接收等算法。(OFDM and a series of code-sharing, including the modulation, pre-coding, channel coding, receiving and other algorithms.)

说明：  实现了FIR的算法，并给出其Lattice结构参数，尤其是利用参考文献实现k=0时的Lattice参数计算问题。(Realized FIR algorithm, and gives the Lattice structure parameters, in particular, the use of Reference to achieve k = 0 when the issue Lattice parameters.)

说明：  matlab下实现对高斯噪声下的小目标的滑窗检测。数据为1000个点，滑窗窗口大小为30，每次滑动一个点的数据。采用的是窗内30个数据先各自平方，然后求和，再除以窗口大小。实验表明能有效检测雷达目标信号。(matlab under Gaussian noise to achieve a small target detection sliding window. Data for 1000 point sliding window window size is 30, each time moving a point of data. Using the data before the window each 30 square feet, and then summed, divided by the window size. Experiments show that the radar target signal can be detected.)

程序是模糊MPPT控制，包括三个模块，光伏电池模块 模拟boost电路模块 (mppt MPPT control program is vague. Consists of three modules, photovoltaic module analog boost circuit module)

说明：  详细讲解EM（期望最大化）算法，并使用混合高斯分布示例编程实现解答(Explain EM (expectation maximization) algorithm in detail, and use mixed Gaussian distribution example programming to realize the solution)

G13Problem optimizition benchmark problem (test problem) in matlab

说明：  语音识别全过程的matlab程序，运行测试能出结果，希望对你们有用，实在没点数才把自己压箱底的东西拿出来,呜呜(The whole process of speech recognition matlab program, run the test to the result, I hope helpful for you, only then it did not point out what their own bottom pressure, the hum)

An image-based classification application satisfying all the aims above has been implemented. It allows for flexible evaluation of SVM classification of facial expressions for arbitrary user-defined emotion categories and various SVM settings.

这是一个仿真单摆非线性振动的程序，可以计算单摆的分岔图。相图。是基于MATLAB开发(this is a program for slove the nonlinear vbration of pendulum.)

fscan 是在matlab里面的一个频率的扫描程序 可以对于一个特定的对象进行频谱的扫描 需要的可以自行下载(matlab at fscan are inside a frequency scanning procedure can be for a specific object to scan the frequency spectrum can download the necessary)
