This text, like its previous four 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.
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.
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. |
