The renowned communications theorist Robert Gallager brings his lucid writing style to the study of the fundamental system aspects of digital communication for a one-semester course for graduate students. With the clarity and insight that have characterized his teaching and earlier textbooks, he develops a simple framework and then combines this with careful proofs to help the reader understand modern systems and simplified models in an intuitive yet precise way. A strong narrative and links between theory and practice reinforce this concise, practical presentation. The book begins with data compression for arbitrary sources. Gallager then describes how to modulate the resulting binary data for transmission over wires, cables, optical fibers, and wireless channels. Analysis and intuitive interpretations are developed for channel noise models, followed by coverage of the principles of detection, coding, and decoding. The various concepts covered are brought together in a description of wireless communication, using CDMA as a case study.

读后感
边听边看，只读书估计读不下来。。。还有图灵网站是下不到答案的，但是gallager的网站上可以下到部分答案。。。够用么？他说This is a subset of solutions that I feel would be valuable for those studying the subject on their own.至于你们信不信，反正我是信了。

用户评价
每一个通信人都应该读一下这本书
评分网上还有作者的MIT公开课，上学时候看的，挺好，基本跟着书来的。印象比较深的是，他提到，有一天他去找香农讨论一个看似很难的问题，香农用层层分解的思路，把那个很难的问题最终转换为若干很简单的东西，根据那些个简单的东西，一层一层回推，最终就把那个难题解决了。
评分Gallager的作品，和他的信息论一样，语言准确且可读性强！
评分比较典型的MIT风格，上来就戳本质，讲得很深，并不适合拿来当第一本数字通信教材。用Proakis的书学习完数字通信课程以后再来看这本书，会有种内功提升的感觉。
