说明：  简要介绍了一下纠错编码的相关基础知识,主要介绍了线性分组码，卷积码，循环码等等(A brief introduction about the basics of error correction coding of the relevant)

说明：  粒子滤波的5个示例程序，对初学者非常有用(5examples for particle filter ,useful for new users)

simulations in matlab especially about filters and a project about the wien bridge signal generator(n=3)

一个QR-RLS算法matlab程序，用于预失真技术。(A QR-RLS algorithm matlab program for pre-distortion technology.)

我的这个源码可以直接绘制一个正圆。方便又实惠哦(mine is good,it can print a circle)

单泡声致发光的中气泡半径的计算及其分析。(Calculation and analysis of single bubble sonoluminescence bubble radius.)

模拟单边带调幅及解调产生300 ~ 3400Hz的调制信号，画出时域波形及频谱；  产生载波信号，频率自定义，画出时域波形及频谱；  产生加性高斯白噪声，画出时域波形及频谱；  单边调幅，画出叠加噪声后的调制信号和已调信号的波形及频谱；  设计滤波器，画出幅频响应图；  解调，画出解调后的信号时域波形及频谱，并对比分析。(Simulation of single sideband amplitude modulation and demodulation )

这个是图像轮廓提取的matlab程序，而且提取完后还能把所有轮廓用不同颜色分开存放到轮廓矩阵cell中，方便用户对感兴趣的轮廓进行操作--张璐奉献(This is the matlab image contour extraction process, but also exhausted all the contours extracted with different colors kept separate from the profile cell in the matrix, user-friendly to operate the contours of interest- Zhang Lu dedication)

实现了SAR目标仿真平台的构建，详细的介绍了如何实现点目标回波数据的仿真和CS程序，并用MATLAB实验了实验平台，能够方便快捷的得到仿真数据。(SAR simulation platform to achieve the goal of building, a detailed description of how to achieve point target echo data simulation and CS program, and an experimental platform to experiment with MATLAB, quick and easy to get the simulation data.)
