PSD-plot

该代码实现了am，f-msk，qpsk，mdpsk(the code achieved am, f-msk, qpsk, mdpsk)

用matlab代码实现的稀疏自编码器，通过可视化步骤，可以看到稀疏编码提取出来的她特征。( sparse autoencoder written by matlab, through visualization step, you can find the features extracted by sparse coding .)

假定一个线性调频信号，作出线性调频信号的时域和频域波形，并对线性调频信号做脉冲压缩(Assuming a linear FM signal, making a linear FM signal in time domain and frequency domain waveforms, and a linear FM signal with pulse compression)

PULSE CODE MODULATION

kalma fileter programme to test

这是一个可用的求权重的程序，所求的是列的权重，作为函数的形式出现，可以直接调用，实在数据处理时编写的，可以直接用。(Seeking weight program is available, ask the weight of the column, as a function of the form appears, you can directly call, really data processing written can be directly used.)

电力系统潮流计算算法，用matlab编写(tidal current)

自相关法基音检测的MATLAB代码。自相关法计算速度较快的自相关函数法检测语音的基音频率，有效剔除了高频共振峰和噪音的影响，其估计基音频率准确性高，稳定性好，运算速度较快。(CAMDF)

经典的EM算法实现，从外国网站上下来的，希望有用(classical EM algorithm may be helpful)

说明：  利用AR模型针对davenport谱的随机风速时程的模拟。(e moving model of the simulated wind speed time history。)
