《数字通信(第五版·英文精简版)》是著者普罗科斯、萨利希多年教学和科研的总结，是一本比较全面、系统、深入论述数字通信理论的经典力作，在学术界有很大的影响，同时也是一本优秀的研究生教材，多年来，国内外许多高等院校普遍采用本书作为信息和通信专业的研究生教材。全书有16章，内容十分丰富，包括：确定与随机信号分析；数字调制方法；AWGN信道的最佳接收机；载波和符号同步；通过带限信道的数字通信；自适应均衡；多信道和多载波系统；数字通信用扩频信号；衰落信道：信道特征与信号传输；多天线系统。

普罗科斯、萨利希编著的《数字通信(第五版·英文精简版)》是在《数字通信(第五版)》的基础上，根据国内的实际教学情况进行精简和改编的。主要的精简原则为：保留信号传输理论内容，舍去信息传输理论内容，并以传统而经典的数字传输理论为主，无线通信为辅。改编的部分主要是根据国内实际教学的常用习惯来进行的。精简后的内容主要涵盖：确定与随机信号分析；数字调制方法；AWGN信道的最佳接收机；载波和符号同步；通过带限信道的数字通信；自适应均衡；多信道和多载波系统；数字通信用扩频信号；衰落信道：信道特征与信号传输；多天线系统。

《数字通信(第五版·英文精简版)》取材新颖，讨论问题系统全面、逐步深入、概念清晰，理论分析严谨、逻辑性强，习题丰富，适合作为信息和通信专业高年级本科生和研究生的教材，也可作为相关专业的教师和科技工作者的参考书。
