将有限元软件到处的数据转换成txt，很好用哦(Full data of the finite element software to convert txt, very easy to use!)

角点检测的一个MATLAB源代码，希望对初学者有点帮助。(corner detection of a MATLAB source code, and I hope to be useful to beginners.)

QAM16在通信系统中是一种简单的调制方式，可以提高频谱利用率，该程序可以恢复QAM16的星座图(QAM16 in a communication system is a simple modulation, spectral efficiency can be improved, the program can resume constellation QAM16)

说明：  加循环前后缀和升采样程序，插入循环前后缀是将每个OFDM符号的前32个数据放到符号尾部，将每个OFDM符号的后32个数据放到符号头部，升采样是通过中间插零的方式实现(Cycle before adding the suffix and lift sampling program, insert the loop before the suffix is ??the first of each OFDM symbol data into the symbolic end of 32, after each OFDM symbol data into the symbols of 32 head or through the middle of the sampling way to achieve zero insertion)

本文主要利用matlab编程工具对直接序列扩频通信的捕获过程进行仿真。仿真主要基于滑动相关法的有关理论,先讨论扩频仿真中起着重要作用的m序列的生成问题,尔后讨论调制信号的产生,然后在信号的捕获中分步讨论,先对捕获的流程进行简单的仿真,再依次加入噪声和多普勒频移后进行捕获仿真(In this paper, using matlab programming tools for direct sequence spread spectrum communication capture process simulation. Simulation of the sliding correlation method is based on the theory, first discuss the simulation plays an important role in spreading the m sequence generation problem, the modulation signal generation and later discussed, and the signal captured by stepping discussion processes the captured first simple simulation, and then followed by adding noise and Doppler frequency shift after the capture simulation)

说明：  利用最速下降法可以求得非线性方程的最优解，运算过程简单易懂。(By using the steepest descent method, the optimal solution of nonlinear equation can be obtained, and the operation process is simple and easy to understand.)
