A simple code for GA

说明：  关于多进制LDPC码的编译码的matlab代码(Ary LDPC codes on the coding and decoding of the matlab code)

程序设计问题和学习有效题目，可以有效提高初学者学习能力。(it can inprove the ability of the learners)

说明：  《载波相位相对定位双差方程原理》验证 《载波相位相对定位单差方程原理》验证 《载波相位相对定位双差方程原理》验证 《载波相位相对定位双差方程原理》验证当基站离流动站很近，并假设流动站概略坐标等于基站坐标，那么双差方程中距离向量就为0(&quot Double difference carrier phase relative positioning equation theory&quot test &quot single-difference carrier phase relative positioning equation theory&quot test &quot double difference carrier phase relative positioning equation theory&quot test &quot double difference carrier phase relative positioning equation principle&quot is verified when the base station from the mobile station near, and assuming that mobile station is equal to the base station coordinates approximate coordinates, so double-differential equation from the vector is 0)

说明：  一篇很好的matlab的PDEtool工具箱使用文献.感兴趣的可以看看.(A good use of matlab toolbox of PDEtool literature. Interested can look at.)

本程序包含四种常用的功率谱计算方法。包括周期图法等。(This program includes four kinds of commonly used calculation method of the power spectrum.Including the periodogram method, etc.)

说明：  Fm调制和仿真，大家可以从这个程序了解到FM的模型的产生，在不同信号不同信噪比之下的比较(fm )
