Principles of Communications, 6th Edition
December 2008, ©2009
This is accomplished by providing overviews of the necessary background in signal, system, probability, and random process theory required for the analog and digital communications topics covered in the book. In addition to stressing fundamental concepts, sections on currently important areas such as spread spectrum, cellular communications, and orthogonal frequency-division multiplexing are provided.
While the book is aimed at a two-semester course, more than enough material is provided for structuring courses according to the needs of the students and the preferences of the instructor.

- Examples illustrating key points in the text included in each chapter. Provides student with illustrations on how to apply theory developed in the text. Assists the instructor in development of material to be used in future chapters.
- Computational Computer Examples included in each chapter. Illustrates the use of the computer for calculation of various performance curves. Allows instructor to have student reproduce performance curves included in text or add to them; the student is taught not to take something on "face value" but to illustrate it for his or her own edification.
- Simulation Computer Examples included in many chapters. Shows student how to use the computer as a simulation tool, thereby allowing waveforms, spectra, and performance curves to be generated. Allows the instructor to illustrate how various performance curves were generated, such as Figures 3.52 and 3.53, or to verify statements in the text that system A, which can't be analyzed, performs worse than ideal system B but that the loss isn't great enough to warrant approximating the ideal system better.
- Chapter summaries arranged as bullet items. Provides a concise checklist for the student to use in reviewing for examinations. Provides a concise checklist for the instructor in seeing if essential points have been covered or in making up examinations.
- Wide variety of problems included at the end of each chapter, categorized according to section. Allows the student to practice on concepts given in text. Allows the instructor to make assignments to check on the students' understanding of presented concepts in class.
