阿诺德变换用于水印算法中，得到了很好的效果，希望大家看看(arnold use in watermarking)

这是我在做浅海水声信道建模时收集的一些资料和程序，有一定的参考价值，分享给大家(This is some of the information and procedures I was doing shallow water channel modeling the collection, there is a certain reference value for everyone to share)

偏微分求解，大全很全面的偏微分求解，显隐式，对比及使用等(Partial differential solution)

这是神经模糊网络中的D-FNN，极其所用到的函数程序。(This is a neuro-fuzzy network in the D-FNN, most of the procedures used in the function.)

过不同方法进行粗糙集属性约简matlab完整程序(rough set matlab program)

说明：  这里面所有源码均为《通信原理——基于Matlab的计算机仿真》（郭文彬 桑林.北京邮电大学出版社）上的，自己录入整理，均可以运行，方便查找(Communication Principle Simulation)

在信号处理中，信号发射时，信号通过载波，调制，以电磁波的形式发射出来 在接收端，射频信号通过天线接收，超外差式等方式进行处理，变频到中频 然后通过数字技术对中频信号进行处理，此时的中频信号采样率很高，多达几十兆赫 而要解调出来的信号很小，此时就要经过滤波来得到我们需要的信号 如果直接设计滤波器，阶数会非常庞大，软件，硬件设备都承受不了 因此，一般常用的技术是进行下变频处理，其主要技术就是通过抽取滤波进行下变频 常用的滤波器就是CIC抽取, 希望可以帮助一些坛友解决基本的问题。 (In signal processing, signal emission, signal through the carrier, in the form of electromagnetic wave modulation, launched In the receiver, rf signals through the antenna, specialized superheterodyne type means such as processing, the frequency conversion to intermediate frequency Then through digital technology of intermediate frequency signal processing, at this time of intermediate frequency signal sampling rate is very high, as many as several decades MHZ But the signal demodulation out is very small, at this time would be passing filter to get what we need signal If design directly filter, order number be colossal, software, hardware equipment all suffer Therefore, the technology is usually used for down-transducer processing, its main technical is by extracting filtering down-transducer Commonly used filter is CIC extraction, the hope can help some friends solve basic problems of the altar.)

自己编写的程序包括 主要是天线的自适应算法仿真(I have written procedures, including all the major adaptive algorithm is the simulation of antenna)
