学习信号处理的经典代码，使用matlab7以上版本，包含了各种滤波器的源代码(Learn the classic signal processing code, the use of more than matlab7 version contains the source code for a variety of filters)

适合卫星通信本科学生借鉴。主要为卫星转发器仿真设计。可以实现上下变频，非线性放大器实现和卫星转发器实现。(Satellite transponder Simulation Design。Achieve Frequency conversion)

边缘检测，用matlab编程。边缘检测是图像处理和计算机视觉中的基本问题，边缘检测的目的是标识数字图像中亮度变化明显的点。图像属性中的显著变化通常反映了属性的重要事件和变化。(Edge detection, using matlab programming. Edge detection is an image processing and computer vision in the basic problems, edge detection is to identify the purpose of the digital image brightness variations obvious point. Image attribute significant changes usually reflect important events and changes in properties.)

t-SNE function。点开即用，封装完好方便，逻辑清晰。t-SNE降维(t-SNE function. It is easy to use and the logic is clear. T-SNE dimensionality reduction)

控制系统模型的建立：将常规PID控制改进为带自适应的模糊PID控制，使控制系统的精度和稳定性有比较好的效果(fuzzy pid control)

是一種用以衡量兩張數位影像相似程度的指標。當兩張影像其中一張為無失真影像，另一張為失真後的影像，二者的結構相似性可以看成是失真影像的影像品質衡量指標。(Is a digital image to measure the similarity of two indicators. Two images when one of them is undistorted image and one for image distortion after the structural similarity between the two images can be viewed as a measure of the quality of the image distortion.)

奇异值差分理论，对输入的信号矩阵化，并对矩阵进行奇异值分解，完成对信号的分析和处理(Singular value differential theory, the matrix of the input signal, and the matrix singular value decomposition, the completion of signal analysis and processing)

向一幅图象中添加符合脉冲分布的噪声，从而为图象噪声分析提供图象噪声模板(to add an image consistent with the distribution of pulse noise, noise for image analysis template image noise)
