通信系统中常用的脉冲编码调制PCM的matlab源代码(PCM)

简单的卡尔曼滤波算法，很适合新手学习，通俗易懂。(Simple Kalman filter algorithm, it is suitable for novices to learn, easy to understand.)

LDPC码的matlab仿真程序，希望对大家有用，不客气，(LDPC codes matlab simulation program, in the hope that useful, at worst,)

蚁群算法的matlab实现程序代码，经过本人实际验证，能够很好的解决一些问题(Ant colony algorithm matlab implementation program code, after I actually verified, can well solve some of the problems)

Source code for gradient algorithm

圆柱体的散射的解析解，及nonlocal效应的对local影响(The impact of the cylinder analytical solution scattering, and nonlocal effects on local)

matlab实现arima算法,这个代码里面有一个循环过程来选择合适的阶(arima algorithe)

说明：  matlab里面使用三倍中误差法消除观测粗差，去除噪声。(matlab error method which uses three times in the elimination of Gross Errors, remove noise.)
