演示matlab如何实现通信遥控等,其中涉及到一些通信方面的知识,请查阅相关资料.()

多信道测量时，处理系统非理想特性的去嵌入程序。(the de-embedding code for a real communication system when doing channel estimation.)

rar文件解压源码,为rarlab公司发布(source code for unrar-5.2.6,uppack the .rar files,for multi-os )

雷达信号中的微多普勒效应这本书的所有源代码，包括原处理信号的dat形式的文件，包括STFT等m文件(The micro-Doppler radar signal effect this book all the source code, including the form of the original signal processing dat files, including documents STFT and other m)

文件多自由度.m为单独的文件，单独执行即可，可以得到一个3自由度的系统受到脉冲作用的结果。 文control.m,plotresult.m,duoziyoudu.mdl为一个完整的程序，先执行control.m，而后执行duoziyoudu.mdl文件，最后plotresult.m文件画出结果。使用的是kobe地震波.(Document multi-degree of freedom. M as a separate document, a separate implementation can, you can get a 3-DOF system are the result of impulse. Text control.m, plotresult.m, duoziyoudu.mdl for a complete procedure, the first implementation of control.m, then the implementation of duoziyoudu.mdl documents, the final document drawn plotresult.m results. Kobe using seismic waves.)

矩量法是求解电磁场边界值问题中一种行之有效的数值方法.它所做的工作是将积分方程化为差分方程,或将积分方程中积分化为有限求和,从而建立代数方程组,故它的主要工作量是用计算机求解代数方程组.所以,在矩量法求解代数方程组过程中,矩阵规模的大小涉及到占用内存的多少,在很大程度上影响了计算的速度.如何尽可能的减少矩阵存储量,成为加速矩量法计算的关键.此处介绍了方法(MoM is the solution of electromagnetic field boundary value problem in an effective numerical method. It is the work done by integral equations into differential equations, or integral equations into a finite sum of points, so as to establish algebraic equations Therefore, it is the main workload of the computer to solve algebraic equations. Therefore, in the moment method for solving algebraic equations, the matrix size relates to the amount of memory, to a large extent affected the speed of calculation. how to maximize the reduction of matrix storage has become accelerated MoM calculation of the key. introduce the method here)

实现基于BPSK的直接扩频信号调制，并显示出各阶段信号波形。(Direct-based BPSK modulated spread spectrum signal, and shows the signal waveform of each phase.)

Matlab得基础教程，其在高等数学，线性代数，数值分析中应用和实现，以及较经典的数学建模。(Matlab was based tutorial, its higher mathematics, linear algebra, numerical analysis and implementation of applications, as well as more classical mathematical modeling.)

该文件能够实现盲信号的分离，分离效果很好，输入为两种信号的非线性叠加，经过仿真效果很明显！(The document can achieve blind signal separation, separation a good effect, input non-linear superposition of two kinds of signals, through simulation effect is obvious!)
