gridfit

传输线的工作状态波形，包括行波和驻波，当参数改变时，传输线的工作状态也因此而改变(The operating state of the waveform of the transmission line, including traveling wave and standing wave, when the parameter is changed, the working status of the transmission line can also be changed)

在Word环境下使用的MATLAB，非常方便，运行速度快(MATLAB uses which under the Word environment, extremely convenient, the running rate is quick)

说明：  在本系统中，信息序列在先经过FSK调制，经过截止频率为25kHz的低通滤波器后（把信号频率限制在25kHz），再进入混频器搬移到更高的频率发送出去，在接收端，用与发送端同步的跳频信号对其进行变频（跳频的解跳处理在此进行），取下边频，然后进行FSK的解调(In this system, the message sequence prior through FSK modulation, through the cut-off frequency of 25kHz after low-pass filter (to limit the frequency 25kHz), and then move into the mixer to a higher frequency to send out, at the receiving end used with frequency hopping synchronization signal transmitter carried on their conversion (FH' s solution to deal with this for jumping), take down side frequencies, then the demodulation of FSK)

课程设计时编写的matlab程序代码，采用了小波去噪的思想，脉冲响应的相关分析算法并检验，包括脚本文件和函数文件形式，随机调制信号下的模拟ppm，这个有中文注释，看得明白，用于时频分析算法，外文资料里面的源代码。 ( Course designed to prepare the matlab program code, Using wavelet denoising thought, Related impulse response analysis algorithm and inspection, Including script files and function files in the form, Random ppm modulated analog signal under The Chinese have a comment, understand it, For time-frequency analysis algorithm, Foreign materials inside the source code. )

多目标优化问题计算，主要用于工程计算，工程优化。(Multi-objective optimization problem and the calculation, mainly for engineering calculations, engineering optimization.)

MPSK_QAM，MPASK下的QAM调制方式，供参考(MPSK_QAM, QAM modulation MPASK under reference)

基于DQPSK差分编码调制解调,希望对你有帮助。(DQPSK modulation and demodulation based on differential encoding, I hope to help you.)
