MATLAB编写的图像直方图处理程序，对输入的图像首先显示它的图像与直方图，然后进行直方图均衡化处理，显示处理后的直方图与图像。(A MATLAB program for image histogram equalization. First input an image and display its histogram. Then equalize the histogram of the input image and display its equalized histogram .)

When you make a DSB_SC Modulation, it is very useful.

产生2fsk或4fsk的调制信号，可以控制带宽，中心频率，噪声，可以观察频谱(this can product signal)

合成孔径雷达sar探测距离相对于孔径功率的MATLAB仿真程序，最后结果以图表形式给出(Synthetic aperture radar sar detection distance with respect to the aperture power MATLAB simulation program, the final result is given in the form of a chart)

基于Matlab系统的信号FFT频谱分析与显示(Matlab FFT-based spectral analysis system signal and display)

有关MPSK调制，传输模型。成型脉冲分为矩形，升余弦脉冲，平方根升余弦脉冲。M的值为2，4和8.所加噪声是高斯白噪声。(Of the MPSK modulation, transmission model. Pulse shape is divided into rectangular, raised cosine pulse, the square root raised cosine pulse. The value of M for 2,4 and 8. The increase in noise is Gaussian white noise.)

无限冲击响应滤波器 (IIR) 实现，涉及一个Butterworth低通滤波器，设计指标为：在通带内频率低于0.2π时，最大衰减小于1dB；在阻带内[0.3π, π]频率区间上，最小衰减要大于15dB (An infinite impulse response filter (IIR) implementation, involves a Butterworth low-pass filter design specifications as follows: in the passband frequencies below 0.2π, the maximum attenuation is less than 1dB in the stopband [0.3π, π] frequency interval , the minimum attenuation greater than 15dB )

一个DE多目标算法，可以绘制相应的pareto前沿(A DE multi-objective algorithm can draw corresponding Pareto frontiers.)
