说明：  这个主要是当前IT流行的C和C++开发的资料。这里稍作整理，(The IT major is currently the popular C and C++ development information. Here a brief order,)

ga tuned input shaper

求序列向量xn的傅里叶变换和离散傅里叶变换并画出它们的幅频特性和相频特性曲线，验证离散傅里叶变换是傅里叶变换的等间隔采样，验证IDFT和DFT的唯一性(Find the Fourier transform of the sequence xn vector and the discrete Fourier transform and draw their amplitude-frequency characteristic and phase-frequency characteristic curve, verify the discrete Fourier transform is the Fourier transform of equally spaced sampling, verification of IDFT and DFT Uniqueness)

用matlab编的俄罗斯方块程序，偶然发现的，编的很有趣(Tetris series with the matlab program, by chance discovered a very interesting series)

说明：  此程序用来进行信道延迟，和序列互相关的。(This procedure used for channel delay, and the sequence of inter-related.)

利用重叠相加法实现线性卷积，其中应用了fft和ifft原理(Use of overlap-add method to achieve linear convolution)

产生多径衰落信道，有6个可分辨径，每径中有25个径形成瑞利信道。(Generate multi-path fading channel, there are six tracks can be distinguished, each track has 25 tracks form a Rayleigh channel.)
