Product Description
Communications technologies increasingly pervade our everyday lives, yet the underlying principles are a mystery to most. Even among engineers and technicians, understanding of this complex subject remains limited. However, there is undeniably a growing need for all technology disciplines to gain intimate awareness of how their fields are affected by a more densely networked world. The computer science field in particular is profoundly affected by the growing… More >>

The book is a well written introduction to its subject. Suitable at the second or third year undergraduate level for engineering majors. All the common transmission methods are explained. Starting with the analog approaches of amplitude modulation and frequency modulation. Then the text goes into the digital ideas of amplitude shift keying, quadrature amplitude modulation, etc. While TDMA and CDMA also are described. These are relevant for cellphones.
The authors go up to, but never quite describe information theory. Nothing about entropy and Shannon’s theorems. What is interesting is how far they have taken the discussion in this absence. For the most part, the book is a collection of definitions. But for a truer understanding of channel capacity and for a comparative analysis of the different methods, and their ultimate limitations, you have to go beyond this book.
