Matlab中几个数值积分函数的比较和优缺点介绍

自学的必备工具之一,通过编程可以练习进行各种生产单位的实践工作(Self taught one of the necessary tools)

对matlab初学者很有帮助，尤其是simulink的爱好者。(Matlab helpful for beginners, especially the simulink lovers.)

复杂网络中，对度分布特征的程序，源数据是邻接矩阵，运行简单，可得出两张图。(complex network, the degree distribution,and it is good job,you can get two graph)

说明：  分析了相位噪声对正交频分复用(OFDM)系统的影响,发现相位噪声不仅产生 通用相角错误(CPE),而且还会产生载波间干扰(ICI),这都使OFDM系统的性能急剧恶 化,因此必须对CPE和ICI进行校正.文中给出了基于MSE准则的CPE校正方法,考虑到 ICI干扰主要来源于相邻信道,进而提出了基于LMS法则的自适应相邻信道干扰消除方 法.整个算法简单高效.仿真结果表明,所提出的算法大大改善了OFDM系统的性能(Phase noise is analyzed for orthogonal frequency division multiplexing (OFDM) systems, the influence of found that phase noise is not only a common phase error (CPE), but also produces the intercarrier interference (ICI), which makes the performance of OFDM system has evil, so must to CPE and ICI. CPE correction method based on MSE criterion are also given in this paper, considering the ICI interference is mainly from the adjacent channel, then was proposed based on the laws of LMS adaptive adjacent channel interference elimination The simulation results show that the proposed algorithm greatly improves the performance of OFDM system)

MATLAB GUI里如何将文件保存成.m文件...(MATLAB GUI)

利用分数阶傅里叶变化进行高分辨率的时频分析的文章，非常不错。(Changes in fractional Fourier using high-resolution time-frequency analysis of articles, very good.)

说明：  用subplot分别在不同的坐标系下作出下列四条曲线，为每幅图形加上标题(subplot were used in different coordinate system to the following four curves for each piece of the title with graphics)

本程序模拟了一个2DPSK发送和接受的完整过程，差分编码采用模2加的方式得到，本次实验采用的是相移键控的方法得到发送信号，2DPSK信号最常用的解调方法有两种，本次实验采用的是极性比较法，先通过2PSK相干解调器，再经过码（反）变换器得到基带信号。 (This program simulates a 2DPSK sending and receiving complete process, differential coding is completed by modulo-2 addition； the experiment using the phase shift keying method to send signals.this experiment is the polarity comparison method,firstly go through the 2PSK coherent demodulator and then pass through code (trans) converter to obtain a baseband signal.)
