说明: Manchester码的编码规则是,如果原始数据为“1”,将其编码成“10”;如果原始数据为“0”,将其编码成“01”。这种编码的特点是每个码元中间都有跳变,低频能量较少,便于接收端提取时钟信息。(Manchester, the coding rule is, if the original data is " 1" , be coded " 10" if the original data is " 0" , be coded " 01." This code is characterized by the middle of each symbol has a jump, low energy less easy to extract the clock information on the receiving end.)

QAM
编写一个含QAM传输的发送和接收模块
1)分别采用复基带仿真和实带通仿真两种形式
a) 实带通仿真时, 载波频率为符号率的4倍
b)发端采用滚降系数0.5的根号升余弦滤波器
2)画出Eb/N0=15dB时的接收波形(收滤波前),取100个采样
3)画出发端输出的眼图和收端过匹配滤波后的眼图(画眼图时不加噪声)
统计误符号率和误比特率与Eb/N0的关系,画出曲线, 与理论计算的曲线相对比
(Prepare to send of one with QAM transmission and receiver module 1), respectively, the complex baseband simulation and the real band-pass simulation in two forms a) the real band-pass simulation, the carrier frequency used for the symbol rate of 4 times b) the originator roll-off factor of 0.5 root raised cosine filter, 2) draw Eb/N0 = 15dB when the received waveform (closing filter), take 100 samples) to draw the originator of the output eye diagram and income side of the eye diagram after the matched filter ( draw the eye diagram without noise) statistics symbol error rate and bit error rate and Eb/N0, draw a curve calculated with the theoretical curve compared)

C8-pi4demo
这个例子将产生并显示pi/2 DQFSK系统中的一些重要信号,仿真这个系统并产生图形输出的MATLAB程序在文件夹中给出。在MATLAB的命令提示符下输入程序名c8-pi4derno后,会绷现一个菜单,用户可通过这个菜单选择以下七个选项中的一个(产生一个图形后,击空格键会显示菜单以便作另一个选择)
1.滤波前的pi/4 DQPSK信号星座图
2.滤波前的pi/4 DQPSK眼图-
3.滤波后的pi/4 DQPSK信号星座图
4.滤波后的pi/4 DQPSK眼图
5.滤波前的同相和正交信号
6.滤波后的同相和正交信号
7.退出程序(返回MATLAB命令提示符)
读者应该仔细研究文件夹中的内容,因为它阐明了很多常见的后处理过程,而且,产生各种图形的代码可用于其他仿真程序的后处理器。
(It is very difficult to describe the MATLAB procedure in english.)
