It is a great pleasure to be asked to write the Preface for this book on trellis decoding of error correcting block codes. The subject is extremely significant both theoretically and practically, and is very timely because of recent devel- opments in the microelectronic implementation and range of application of error-control coding systems based on block codes. The authors have been notably active in signal processing and coding research and development for several years, and therefore very well placed to contribute to the state of the art on the subject of trellis decoding. In particular, the book represents a unique approach to many practical aspects of the topic. As the authors point out, there are two main classes of error control codes: block codes and convolutinal codes. Block codes came first historically and have a well-developed mathematical structure. Convolutional codes come later, and have developed heuristically, though a more formal treatment has emerged via recent developments in the theory of symbolic dynamics. Max- imum likelihood (ML) decoding of powerful codes in both these classes is computationally complex in the general case; that is, ML decoding fails into the class of NP-hard computational problems. This arieses because the de- coding complexity is an exponential function of key parameters of the code.
Symbolic dynamics is a rapidly growing area of dynamical systems. Although it originated as a method to study general dynamical systems, it has found significant uses in coding for data storage and transmission as well as in linear algebra. This book is the first general textbook on symbolic dynamics and its applications to coding. Mathematical prerequisites are relatively modest (mainly linear algebra at the undergraduate level) especially for the first half of the book. Topics are carefully developed and motivated with many examples, and there are over 500 exercises to test the reader's understanding. The last chapter contains a survey of more advanced topics, and a comprehensive bibliography is included. This book will serve as an introduction to symbolic dynamics for advanced undergraduate students in mathematics, engineering, and computer science.
Published annually and currently in its 21th edition, Coding for Pediatrics is the signature publication in a comprehensive suite of coding products offered by the American Academy of Pediatrics (AAP). This AAP exclusive complements standard coding manuals with pediatric-specific documentation and billing solutions for pediatricians, nurse practitioners, administration staff, and pediatric coders. This year's edition has been fully updated and revised to include all changes to the 2016 Current Procedural Terminology (CPT(R)), complete with accompanying guidelines for their application. The numerous clinical vignettes and examples featured in the book, as well as the many coding pearls included throughout, have also been fully revised and revisited.Coding for Pediatrics, 2016 continues to provide guidance on ICD-10-CM transition including coding tips highlighting key conventions and documentation elements to support specific and accurate ICD-10-CM code selection. Other updates for this edition include Detailed information on new and revised CPT(R) codes for 2016 includingProlonged clinical staff timeRemoval of impacted cerumen with irrigation or lavageRevision of photo-screening servicesNew chapter on enhanced quality and pay for performanceExpanded coding resources including articles for the AAP Pediatric Coding Newsletter, coding fact sheets, sample appeal letter, denial tracking tool, and moreAll clinical vignettes presented with corresponding ICD-10-CM codes.
