Coding and information theory

From rear cover notes: "Richard W. Hamming's many years of rich experience in computer science - in research at Bell Laboratories and in teaching at the Naval Postgraduate School - have helped make possible this long-needed treatment of both coding and information theory in a single, clearly written, and well organized volume. Completely self-contained, CODING AND INFORMATION THEORY uses only the most elementary calculus and minimal amounts of probability theory; its chapters require of the reader no specialized or advanced training in mathematics, electronics, or computer sciences. The theories, proofs, and examples presented here are based on many techniques developed quite recently - in fact, some of them published for the first time in a book at this introductory level...."
