pitch detection with correlation

frft函数的一种matlab实现，可以用于LFM信号处理和图像处理(frft function in matlab)

说明：  对给定的数据，利用PCA求取数据中主分量(Given the data, using principal component in the PCA data to strike)

说明：  很好用的小波分解程序，简单，实用，对初学者很有帮助。(Nice wavelet decomposition program, for beginners helpful.)

直接序列扩频就是直接用具有高码率的扩频码序列在发端去扩展信号的频谱。而在收端，用相同的扩频码序列去进行解扩还原成原始的信息。(Direct Sequence Spread Spectrum is the direct use of the spreading code sequence with a high rate in the originator to expand the spectrum of the signal. Receiving end, using the same spreading code sequence to despread the broadening of the spread spectrum signal to restore the original information.)

动态中继选择和功率分配策略，讨论在不同策略下的功率分配，寻找能使总的功耗最小的方法。(Dynamic relay selection and power allocation strategies discussed in different power allocation strategies, seeking to make the total power consumption is minimal approach.)

白噪声背景下，均匀圆阵列的波束形成，并用三维形式显示出来(White noise background, the uniform circular array beamforming, and displayed three-dimensional form)

基于MATLAB自编kpca和pca源程序，内附运行数据，多次运行无误。谢谢(Based on MATLAB and self kpca pca source, containing operating data, multiple runs correctly. Thank you)

利用matlab/simulink 实现两路信号合并(use matlab/simulink to merge two signals)

一篇学位论文，基于DSP的电力有源滤波器研究。用matlab仿真，并设计了模拟电路。(Write a dissertation, DSP-based Active Power Filter. Using matlab simulation, and design analog circuits.)
