一个灰色模型的matlab实现 gray

This code is about plotimaging in seismic data.

说明：  自己编写的信号产生和处理软件，以matlab7为平台。可以实现确定信号和非确定信号的产生，各种滤波器的设计，对信号的频谱分析，滤波后信号的频谱分析等功能。有利于信号与系统、数字信号处理相关课程的学习与理解。(themselves prepared and have the signal processing software to matlab7 platform. Determine signal can be achieved and identify signals the emergence of various filter design, the signal spectrum analysis, after filtering signals in the spectrum analysis capabilities. Help signal and systems, digital signal processing-related courses of study and understanding.)

说明：  用Matlab编写的TCM+8PSK，并计算误比特率(TCM+8PSK，Matlab)

说明：  华为的5G非正交多址（NOMA）方案SCMA的仿真(Huawei's 5G non-orthogonal multiple access scheme SCMA simulation)

可以得到很精确的幅值、频率、相位估计，相控阵天线的方向图（切比雪夫加权），matlab开发工具箱中的支持向量机，直线阵采用切比学夫加权控制主旁瓣比，滤波求和方式实现宽带波束形成，数据模型归一化，模态振动。( You can get a very accurate amplitude, frequency, phase estimation, Phased array antenna pattern (Chebyshev weights), matlab development toolbox support vector machine, Linear array using cut than learning laid upon the right control of the main sidelobe ratio, Filtering summation way broadband beamforming, Normalized data model, modal vibration.)

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 carry 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.)
