进行FFT变换，在此基础上作频谱分析、功率谱分析等。(FFT transform, on the basis for spectrum analysis, power spectrum analysis.)

image rotate using hough transform to detect the edge of image.

识别不同的调制方式，例如AM，psk等。(Identify the different modulation methods, such as AM, psk and so on.)

说明：  这个是MATLAB实现Hough变换的程序。有基本的Hough变换的理解程序，也有使用Hough变换来检测信号的程序(This is the realization of Hough Transform MATLAB procedures. Hough transform a basic understanding of procedures, have also used the Hough transform to detect the signal process)

说明：  SAR雷达，点目标仿真，程序+文献，包教包会(SAR radar, point-target simulation, the program+ documentation.)

说明：  利用Matlab及Simulink建立仿真系统，对PCM量化信噪比进行仿真测试，要求对输入的正弦波进行采样、量化和PCM编码，计算并画出量化信噪比曲线，比较量化信噪比理论值与实际值。(Using MATLAB and Simulink to set up simulation system to simulate and test the quantized signal-to-noise ratio of PCM, it is required to sample, quantize and PCM code the input sine wave, calculate and draw the quantized signal-to-noise ratio curve, and compare the theoretical value and the actual value of the quantized signal-to-noise ratio.)
