Title: Definitely not an "introduction"
Review: This was the textbook for my Signal Detection & Estimation class and I have to say that I found it to be nearly useless. It is not an introductory text; it is a reference text for people who already are familiar with the topics covered. If I had trouble understanding our professor's discussion of a particular topic, this text was no help at all in clearing up my confusion. The authors frequently leave out key parts of proofs and insert them as exercises at the end of the chapter.
Is the review positive or negative?
