现代通信信号在matlab中的实现以应用程序(good)

说明：  计算均方误差MSE信噪比SNR峰值信噪比PSNR绝对平均误差的matlab函数(Calculate the mean square error MSE, SNR is the peak signal to noise ratio PSNR absolute average error of Matlab functions)

数字信号处理实验内容，编写能够实现fft的matlab程序，并与系统自带的fft相比较。在文件mysecond.m中注释部分给出多种fft实现方法及代码，未拆分成多个m文件(Digital signal processing experiment content, the preparation can be achieved fft matlab program, and compared with the system comes with the fft. The comment section file mysecond.m give multiple fft to achieve method and code into multiple m 未拆)

该Matlab算法，可以实现振动数据的文件的读取，进而可以进行时频分析，得到信号特征值(The Matlab algorithm can achieve vibration data of the document read, in turn, can be time-frequency analysis, Signal Characteristics)

I am submitting my Computational science and engineering assignment #3 based on SVD/PCA.The zip file contains matlab codes of Exercise no:1 and Exercise no:3 as program_1.m and program_3.m files respectively. I have made a separate reports for the above said two exercises as Report_problem1 and Report_problem3, both in pdf format. Please find the attached zip file.

灵敏度分析源程序，可用于结构模型修正，但仅运用了自振频率信息，没有运用振型信息(Sensitivity analysis of source code, can be used for structural model updating, but only the use of natural frequency information, there is no information on the use of modal)

传感器网络探测声信号通过特征提取进行目标设别分类(Sensor network to detect acoustic signals through the feature extraction for target-based classification of other)

MATLAB做网络优化，先生成一个随机的邻接矩阵，然后画出改图。(MATLAB to do network optimization, sir into a random adjacency matrix, and then draw the reform plan.)

speech compression techniques

OFDM比较经典的源码程序，包含了整个系统的仿真，及性能的分析(OFDM more classic source programs, including the simulation of the entire system, and performance analysis)
