matlab实现几种基本的通信仿真技术 (to achieve basic communication matlab simulation of several)

这个是用MATLAB中的SIMULINK做成的PCM编码器,使用MATLAB实现PCM编码和解码.(This is in SIMULINK with MATLAB made PCM encoder, the use of MATLAB realize PCM encoding and decoding.)

说明：  根据滤波器指标选择合适的窗函数，计算窗函数的长度N，调用MATLAB函数fir1设计一个FIR低通滤波器。并编写程序，调用MATLAB快速卷积函数fftfilt实现对xt的滤波。绘图显示滤波器的频响特性曲线、滤波器输出信号的幅频特性图和时域波形图。  (Select the appropriate indicators according to filter window function, calculate the length of window function N, called MATLAB function fir1 design a FIR low-pass filter. And programming, call MATLAB functions fftfilt achieve fast convolution filtering xt. Graphics filter frequency response curve, the filter output signal amplitude and frequency characteristics of maps and time-domain waveform.  )

matlab codes given for various applications.

活塞式压缩机排气管道压力脉动计算matlab程序(Matlab program to calculate the pressure pulsation of piston compressor outlet pipe)

利用Matlab实现的有限差分方法，这是一个m文件下载即可使用。(A simple code for finite difference method)

this is a mass-spring system that show the animation of mass on vertical spring by changing the initial values

求解非线性薛定谔方程中自相位调制SPM,其中数据可以自行设定。有注释。(nonlinear equation for SPM)

可以将matlab中的mat文件转换成txt文件，方便其他的应用程序调用。(Mat files can be converted into a txt file and facilitate the application calls.)
