信息论与编码理论是研究信息的量化、传输和存储的数学原理，涵盖数据压缩、错误检测与纠正等内容，在通信工程及计算机科学中具有重要应用价值。
Robert J McElieces revised edition is tailored for students and provides a comprehensive introduction to the fundamental concepts in information theory and coding. This field was developed to address the core challenge of communication: accurately reproducing messages at one location that were selected elsewhere, either exactly or approximately.
The book begins with an introductory overview that simplifies the concept of coding for readers new to the subject. Following this are detailed discussions on channel and source coding theorems, which form the backbone of information theory. The text also delves into specific coding schemes used in both channel and source coding contexts.
Suitable for self-study or as a course textbook at either graduate or undergraduate levels, it includes numerous worked examples and hundreds of problems to aid understanding. Readers with some background knowledge of probability and linear algebra will find the exposition clear and accessible.
