Due to a steady flow of requests over several years, Springer-Verlag now
provides a corrected reprint of this text. It is designed to serve as a
text for a first semester graduate level course for students in digital
communication systems. As a pre- requisite, it is presumed that the
reader has an understanding of basic probability and stochastic
processes. The treatment of digital communications in this book is
intended to serve as an introduction to the subject. Part one is a
development of the elements of statistical communication theory and
radar detection. The text begins with a general model of a communication
system which is extensively developed and the performance analyses of
various conventional systems. The first part also serves as introductory
material for the second part of the text which is a comprehensive study
of the theory of transmitter optimization for coherent and noncoherent
digital commu- nication systems, that is, the theory of signal design.
