Digital and Analog Communication Systems 8th Edition by Leon W. Couch | PDF Free Download.
Continuing the tradition of the first through the seventh editions of Digital and Analog Communication Systems, this eighth edition provides the latest up-to-date treatment of digital communication systems.
It is written as a textbook for junior or senior engineering students and is also appropriate for an introductory graduate course.
It also provides a modern technical reference for the practicing electrical engineer. A Student Solutions Manual contains detailed solutions for over 100 selected end-of-the-chapter homework problems.
For the selected problems that have computer solutions, MATLAB solution files are available for downloading from the Web.
To download the Student Solutions Manual and the MATLAB files, go to www.pearsonhighered.com/couch.
One major change for this eighth edition is the addition of more than 100 examples distributed throughout the chapters of the text.
Students are always asking for more examples. Most of these new examples have a problem description that consists of only a few lines of text.
The solutions for these examples are contained within MATLAB files (downloaded from the Web site given earlier).
These files include the procedure for the solution (as described by comment lines in the MATLAB program) and produce computed and plotted solutions.
This presentation procedure has several advantages. First, the description for each example takes only a few lines in this textbook, so the book will not be extended in length.
Second, the student will have the experience of learning to work with MATLAB (as demonstrated with the example solutions).
Clearly plotted results, which are better than hand calculations, are given. The student can also vary the parameters in the MATLAB example to discover how the results will be affected.
The author believes that this approach to examples is a great innovative teaching tool. To learn about communication systems, it is essential to first understand how communication systems work.
Based on the principles of communications that are covered in the first five chapters of this book (power, frequency spectra, and Fourier analysis), this understanding is motivated by the use of extensive examples, study-aid problems, and the inclusion of adopted standards.
Especially interesting is the material on wire and wireless communication systems. Also of importance is the effect of noise on these systems,
Since, without noise (described by probability and random processes), one could communicate to the limits of the universe with negligible transmitted power.
In summary, this book covers the essentials needed for the understanding of wire and wireless communication systems and includes adopted standards. These essentials are:
• How communication systems work: Chapters 1 through 5.
• The effect of noise: Chapters 6 and 7.
• Wire and Wireless Communication Applications: Chapter 8.
This book is ideal for either a one-semester or a two-semester course. This book emphasizes basic material and applications that can be covered in a one-semester course, as well as the essential material that should be covered for a two-semester course.
This emphasis means that the page count needs to be limited to around 750 pages. For a book with a larger page count, it is impossible to cover all that additional material, even in a two-semester course.
(Many schools are moving toward one basic course offering in communications.) Topics such as, coding, wireless signal propagation, WiMAX, and Long Term Evolution (LTE) of cellular systems are covered in this book.
In-depth coverage of important topics such as these should be done by additional courses with their own textbooks.
For a one-semester course, the basics of how communication systems work may be taught by using the first five chapters (with selected readings from Chapter 8).
For a twosemester course, the whole book is used. This book covers practical aspects of communication systems developed from a sound theoretical basis.
