Channel-Coding

说明：  一个使用matlab进行音频信息处理的实例，对输入的语音信号，进行合成与分析。(Using matlab audio examples of information processing, the input voice signal, to carry out synthesis and analysis.)

制作红色小球沿一条带封闭路径的下旋螺线运动的实时动画(production of a small red ball with a closed along the path under the rotating spiral movements of real-time animation)

用MATLAB实现AGC，并且还有Word的文字说明，已经在MATLAB上实现过了。(MATLAB implementation by AGC, and there are Word' s text has been realized in MATLAB before.)

说明：  adpcm编码，包括了普通的编码和g.721协议的编码。(adpcm encoding&decoding)

说明：  计算均方误差MSE信噪比SNR峰值信噪比PSNR绝对平均误差的matlab函数(Calculate the mean square error MSE, SNR is the peak signal to noise ratio PSNR absolute average error of Matlab functions)

最小选择恒虚警检测——SO-CFAR检测器：包括对于无目标、仅有噪声的信号进行SO-CFAR检测的仿真，以及对于含目标、且在瑞利杂波背景下的CA算法仿真。一些程序主要是为了绘图，画出SO-CFAR检测过程中的信号波形以及检测门限对比图；而另一些程序是为了计算SO-CFAR检测过程中的检测概率和虚警概率。(SO-CFAR detectors: simulations of detection to signals with no target but noise only, as well as signals with target and the background of Rayleigh clutter. Some programs are aimed at giving pictures of the signals and detectiong threshold in the process of detection using SO-CFAR algorithm, while other programs are aimed at calculating the detecting rate and false alarm rate of SO-CFAR algorithm.)

数学建模各种算法资料及MATLAB源码，包括各种算法分析比较(Various algorithms of mathematical modeling data and MATLAB source code, including a variety of algorithm analysis and comparison)

It is a matlab simulation code about OFDM
