对正选信号进行仿真，画频谱图，并分别在时域和频域对信号延迟。(Positive selection signal delay simulation)

OFDM and CDMA combination for high speed transmission

单缝衍射，白光重现。大学物理很好的演示示例。自编。(Single slit diffraction, the white light to reproduce.University physics demonstrating example very well.The self-made.)

利用最小二乘算法实现对三维平面的拟合，计算多重分形非趋势波动分析matlab程序,最小均方误差等算法的MSE的计算。( Least-squares algorithm to fit a three-dimensional plane, Calculation multifractal detrended fluctuation analysis matlab program, Minimum mean square error MSE calculation algorithm.)

空域滤波是在图像空间中借助模板对图像进行领域操作，处理图像每一个像素的取值都是根据模板对输入像素相应领域内的像素值进行计算得到的。空域滤波基本上是让图像在频域空间内某个范围的分量受到抑制，同时保证其他分量不变，从而改变输出图像的频率分布，达到增强图像的目的(failed to translate)

1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(1. Produce sine wave, square wave, and the white noise signal with Matlab, and their time-domain waveform display 2. FFT transform, display each spectrum, where the sampling rate, frequency, length optional data 3. RMS to make maps of the three signals, power spectrum, as well as the number of RMS map 4. Restored by inverse Fourier transform IFFT signal and displays the time domain waveforms sinusoidal signal recovery)

try this for pq improvmnett

its a uav autopilot simulation project but not so complete

BFT,正交傅里叶变换，用于检测线性调频斜率的方法。仿真与论文结果一致。(BFT, orthogonal Fourier transform for detecting the slope of the linear frequency modulation method. Simulation results are consistent with the thesis.)
