PSK31 Model with Symbol Timing and Carrier Recovery(This model implements a communication standard known as PSK31. The transmit portion of the model can either synthesize the PSK31 signal, or use real world signals that were captured as Wave files. The receiver features include: Automatic Frequency Control, Automatic Gain Control, Symbol Timing recovery with a fractionally spaced Farrow interpolator, Decision Directed Carrier Phase Lock Loop, dbsk or dqpsk demodulation with FEC. References are provided in the Model.)

该程序是VCO的simulink不同实现。设置不同的参数可得到不同的仿真效果。(that the procedure was different VCO Simulink achieve. Set up different parameters can be obtained simulation results.)

对matlab ODE的求解进行了详细的分析，并带有详细的例子（代码）可用来练习。(Matlab ODE solution on a detailed analysis, with detailed examples (code) can be used to practice.)

signal processing for radar such az range, doppler, gain and all fundamental feature.

通用的floyd算法程序，能够很好地解决最短路径问题，同时给出最短路的具体路径。(Floyd algorithm universal procedures, able to solve the shortest path problem, shortest path at the same time given the specific path.)

本软件主要用于结构的时域试验模态分析，包括单输入单输出，单输入多输出和多输入多输出程序设计。传统的模态分析软件大多是基于频域分析方法，需首先对采样信号进行Fourier 变换。本软件使用实测时域信号，无需Fourier变换，可以避免由于信号截断而引起泄露、出现旁瓣、分辨率低等问题对辨识精度的不利影响。此外，节省了计算机运算时间，可以对实际工况状态下的结构进行在线参数识别。(This software is mainly used for the structure of time-domain experimental modal analysis, including single-input single-output, single-input multiple-output and multiple-input multiple-output programming. Traditional modal analysis software are mostly based on frequency domain analysis, needed first sampled signal Fourier transform. The software uses the measured time-domain signal without the need for Fourier transform, avoid truncated because of the signal caused by leaks, there sidelobes and low resolution of the issue of adverse effects on the identification accuracy. In addition, the savings in computing time, to the actual condition of the structure of the state-line parameter identification.)

一种比较好用的音频水印嵌入程序，基于MATLAB实现的。(A relatively easy to use audio watermark embedding process, based on the MATLAB implementation.)
