Keeping up to date with the most current technologies in the field is essential for all effective electrical and computer engineers. The updated 7th edition of Principles of Communications presents the reader with more in-chapter examples, providing for a more supportive framework for learning. Readers are exposed to digital data transmission techniques earlier in the book, so they can appreciate the characteristics of digital communication systems prior to learning about probability and stochastic processes. They will also find expanded forward error correction code examples, and additional MATLAB problems.

对所有有效的电气和计算机工程师来说，跟上该领域的最新技术是必不可少的。更新后的《通信原理》第7版为读者提供了更多的章内实例，为学习提供了更多的支持性框架。读者在书中较早地接触到了数字数据传输技术，因此他们可以在学习概率和随机过程之前体会到数字通信系统的特点。他们还将发现更多的前向纠错码实例，以及更多的MATLAB问题。
