AWGN_LDPC

alpha-beta滤波器是一种很实用的滤波器，可以和卡尔曼滤波，信息滤波器做比较，对于初学者有很大帮助(alpha-beta filter is a very practical filter can Kalman filter, the information filter comparison, are very helpful for beginners)

指纹识别技术的matlab源程序。可以基于这些代码进行二次开发。在matlab中，设置当前的目录为工作目录，在命令行中输入fpextractdemo，即可运行程序。(Matlab source fingerprint recognition technology. Can be based on the code for secondary development. In matlab, set the current directory as working directory, the command line, enter fpextractdemo, you can run the program.)
