·本书通过自上而下的反向教学方法突出数字通信中的传输问题，直接切入了数字通信核心。
![内容简介]()
本书内容全面，易于理解，通过自上而下的反向教学方法来讲授数字通信的基础知识。这种独特的教学方法突出数字通信中的传输问题，在讲述发射机之前先教授接收机的知识。这样做直接切入了数字通信核心问题，使学生能以最少的背景知识快速、直观地进行学习。从解码器的决策问题开始，涵盖不同信道的接收机设计、硬件设计折衷、卷积编码与维特比解码以及带通通信，书中对系统级设计和实际工程应用进行了详细讲授，并且通过大量示例、作业问题和MATLAB仿真练习来帮助读者自学。本书既可作为通信类专业高年级本科生和研究生教材，又可供工程技术人员参考。
