The purpose of this book is to introduce the reader to the basic theory
of signal detection and estimation. It is assumed that the reader has a
working knowledge of applied probability and random processes such as
that taught in a typical first-semester graduate engineering course on
these subjects. This material is covered, for example, in the book by
Wong (1983) in this series. More advanced concepts in these areas are
introduced where needed, primarily in Chapters VI and VII, where
continuous-time problems are treated. This book is adapted from a
one-semester, second-tier graduate course taught at the University of
Illinois and at Princeton University. However, this material can also be
used for a shorter or first-tier course by restricting coverage to
Chapters I through V, which for the most part can be read with a
background of only the basics of applied probability, including random
vectors and conditional expectations. Sufficient background for the
latter option is given for example in the book by Thomas (1986), also in
this series. This treatment is also suitable for use as a text in other
modes. For example, two smaller courses, one in signal detection
(Chapters II, III, and VI) and one in estimation (Chapters IV, V, and
VII), can be taught from the materials as organized here. Similarly, an
introductory-level course (Chapters I through IV) followed by a more
advanced course (Chapters V through VII) is another possibility.
