用fdatool设计一个50Hz陷波器，导出系数，编程，对原始信号signal.txt进行滤波。 本程序为Matlab程序。(50Hz with fdatool design a notch filter, export coefficient, programming, filtering the original signal signal.txt.)

三个txt数据文件的意义及其数据格式举例 97县名称号码、纬度、经度(Txt data files of three of the significance of the data formats, for example the name of 97 the county number, latitude, longitude)

介绍了数字通信中的QPSK调制解调的原理，通过用Matlab编写脚本程序对QPSK通信系统的发射和接收过程的具体实现进行模拟仿真，绘出信号在理想信道和加噪信道中模拟传输时的时域图，并对各模块进行了频谱分析，所得到的结果与 理论基本相符，对于理解QPSK系统的性能并在系统的实际应用上作进一步的设计，提供了有效的参考依据。 (The introduction was done with the principle of the QPSK modulation and demodulation in digital communications，a script was written by using Matlab program to CalTy out a simulation of the QPSK communication system．which contains the concrete realization of transmit and receive process．The time-domain diagram is drew separately when the signal transmits in the ideal channel and in the channel with noise，spectral analysis of each module is also done，the results obtained with theoretical results in the main，which provides an effective frame of reference for understanding the performance of QPSK systems，and the practical application in the system to make further designed．)

数学建模MATLAB必备程序源代码.从matlab菜鸟，一路飙升~~~~后来参加比赛拿奖几乎全靠它了！！尤其是里面的国赛真题的源代码，值得研究~~对于学习数学建模的朋友们，有极大的帮助(MATLAB Mathematical modeling necessary source code matlab rookie, soared almost winning the prize ~ ~ ~ ~ later race depends on it! ! Especially inside the country Zhenti game' s source code, it is worth learning mathematical modeling study ~~ friends, a great help)
