Communication systems : an introduction to signals and noise in electrical communication
This text, like its previous three editions, is an introduction to communication systems
written at a level appropriate for advanced undergraduates and first-year graduate
students in electrical or computer engineering. New features in this edition
include the introduction of two other authors, Professors Rutledge and Crilly, to provide
additional expertise for topics such as optical links and spread spectrum.
An initial study of signal transmission and the inherent limitations of physical
systems establishes unifying concepts of communication. Attention is then given to
analog communication systems, random signals and noise, digital systems, and
information theory. However, as indicated in the table of contents, instructors may
choose to skip over topics that have already been or will be covered elsewhere.
Mathematical techniques and models necessarily play an important role
throughout the book, but always in the engineering context as means to an end.
Numerous applications have been incorporated for their practical significance and
as illustrations of concepts and design strategies. Some hardware considerations are
also included to justify various communication methods, to stimulate interest, and to
bring out connections with other branches of the field.
The assumed background is equivalent to the first two or three years of an electrical
or computer engineering curriculum. Essential prerequisites are differential equations,
steady-state and transient circuit analysis, and a first course in electronics.
Students should also have some familiarity with operational amplifiers, digital logic,
and matrix notation. Helpful but not required are prior exposure to linear systems
analysis, Fourier transforms, and probability theory.
