(Error-controlled coding techniques are used to detect and/or correct errors that occur in the message transmission in a digital communications system. Wireless personal channels used by mobile communications systems and storage systems for digital multimedia data all require the implementation of error control coding methods. Demonstrating the role of coding in communication and data storage system design, this text illustrates the correct use of codes and the selection of the right code parameters. Relevant decoding techniques and their implementation are discussed in detail. Providing communication systems engineers and students with guidance in the application of error-control coding, this book emphasizes the fundamental concepts of coding theory while minimising the use of mathematical tools.
* Reader-friendly approach ti coding in communication systems providing examples of encoding and decoding, information theory and criteria for code selection
* Thorogh descriptions of releva)

主要是实现调制识别,区分几种常用的数字调制信号。含有两个文件夹 其一为特征参数的仿真;其二为正确识别率的仿真。文件夹key feature simulink中:
运行程序会得到各特征参数之间区分图 从图中可看到特征参数的有效性,见图。
文件夹classification rate simulink中:运行main.m文件 可以得到正确识别率 见图。(It is mainly to realize modulation recognition and distinguish several commonly used digital modulation signals. The simulation of two folders is one of the characteristic parameters, and the second is the simulation of the correct recognition rate. In the folder key feature Simulink:
The running program will get the validity of the feature parameters that can be seen from the diagram, as shown in the diagram.
Folder classification rate Simulink: running the main.m file can get the correct recognition rate.)
