From the Foreword: For some years coding theory has played an increasingly central role in the deliberations of communication system engineers. Its importance stems from the bounds that it establishes on what can and cannot be accomplished. The authors have recently been engaged in investigating the problem of designing systems whose performance approaches these bounds. The primary objective of this monograph is to report upon this research. Although the mathematical problems of coding theory become progressively less tractable the closer the theory is pushed towards the physical realities of communication, the basic concepts of coding are not unmanageable. We have chosen here to formulate sequential decoding in the simplest terms that suffice to illustrate its major attributes. Our basic concern, however, is communication engineering. We have, accordingly, attempted in Chapter 1 to relate coding theory to the problem of data communication. In Chapter 6 we discuss the extension of the concepts to fairly realistic channel models, and indicate the range of possible engineering applications. For convenience of reference, in Chapter 2 we survey important prior results that are essential to the sequel. In Chapters 3 and 4 we discuss sequential decoding and encoding, respectively. In Chapter 5 we present the experimental results that have been obtained, and discuss modifications of the decoding procedure. Relevant mathematical details are covered in the Appendix. The monograph is self-contained. It requires that the reader have an elementary knowledge of calculus and probability theory. Background experience in communication engineering will be generally helpful. The principles of information theory that underlie the research reported here are the subject of Robert M. Fano' s forthcoming book Transmission of Information.1 The authors are happy to have this opportunity to express their gratitude to Professors Peter Elias, Robert M. Fano, and Claude E. Shannon. Without their inspiration, guidance, and occasional goading, this work would have been neither undertaken nor accomplished. --John M.
