these are the Mtlab functions to plot the figures in the book Communication system (by Haykin)

这是在数值计算时经常用的样条插值的程序，能够在在MATLAB环境下直接运用。(This is the numerical calculation frequently used spline interpolation procedures in the MATLAB environment direct use.)

4阶龙格库塔方程，给出了一个实例，并且写出详细的步骤和过程，看到就能会。(4-order Runge-Kutta equations, given an instance, and write detailed steps and processes that can be.)

这个程序源码是用来对pllpost进行仿真真的，该思想一种基于多方面的考虑 可直接使用。 (This program source code is used to pllpost simulation is really the thought based on various considerations can be used directly.)

如何利用计算机技术对连续系统和离散系统进行模拟。为研究模拟提供极为适合的手段(How to use computer technology to the continuous and discrete systems simulation. Very suitable for the study provided a means of simulation)

matlab编写,eeglab软件(Matlab prepared eeglab software)

实现自适应滤波功能 回声抵消和语音降噪功能(Adaptive filtering echo cancellation)

数字基带信号的传输是数字通信系统的重要组成部分。在数字通信中，有些场合可不经过载波调制和解调过程，而对基带信号进行直接传输。HDB3码的作用是对数字基带信号进行编码，便于在接收端对定时分量的提取。(Digital baseband signal transmission is an important part of digital communication system. In digital communication, some occasions without carrier modulation and demodulation process, and to direct transmission baseband signal. HDB3 code is used to encode digital baseband signal, facilitate at the receiving end of timing component extraction. )
