"This book offeres an account of the important results derived by the Shannon approach to the field. Intended as a text for graduate students and as a reference for active scientists, it emphasizes techniques useful in estimating the probability of decoding error, the fidelity of information reproduction, and the complexity of coder and decoder instrumentation. Much of the basic material included has not been published previously. The word "Probabilistic" in the title indicates that most of the codes introduced are non-algebraic in character and that their performance properties are derived by probabilistic methods."
