现代编码理论汤姆·理查森(Tom Richardson) 著This book is all about iterative channel decoding.Two other names which are often used to identify the same area are probabilistic coding and codes on graphs.Itera-tive decoding was originally conceived by Gallager in his remarkable Ph.D.thesis of 1960.Gallager's work was,evidently,far ahead of its time.Limitations in com-putational resources in the 1960 were such that the power of his approach could not be fully demonstrated,let alone developed.Consequently,iterative decoding at-tracted only passing interest and slipped into a long dormancy.It was rediscovered by Berrou,Glavieux,and Thitimajshima in 1993 in the form of turbo codes,and then independently in the mid iggos by MacKay and Neal,Sipser and Spielman,as well as Luby,Mitzenmacher,Shokrollahi,Spielman,and Stemann in a form much closer to Gallager's original construction.Iterative techniques have subsequently had a strong impact on coding theory and practice and,more generally,on the whole of commu-nications.The title Modern Coding Theory is clearly a hyperbole.There have been several other important recent developments in coding theory.To mention one prominent example: Sudan's algorithm and the Guruswami-Sudan improvement for list de-coding of Reed-Solomon codes and their extension to soft-decision decoding have sparked new life into this otherwise mature subject.So what is our excuse? Iter-ative methods and their theory are strongly tied to advances in current comput-ing technology and they are therefore inherently modern.They have also brought about a break with the past.Moreover,the techniques are influencing a wide range of applications within and beyond communications,connecting that area with many modern topics in,among others,statistical mechanics and complexity theory.Nev-ertheless,the font on the book cover expresses the irony that the roots of moderncoding go back to a time when typewriters ruled the world.The field ofiterative decoding has not settled in the same way that classical cod-ing has.There are nearly as many flavors ofiterative decoding systems-and graphi-cal models to represent them-as there are researchers in the field.We have therefore decided to focus more on techniques to analyze and design such systems rather than on specific instances.In order to present the theory,we have elected Gallager's orig-inal ensemble oflow-density parity~check (LDPC) codes as a representative exam-ple.This ensemble is perhaps the most elegant example and it provides a framework within which the main results can be presented easily.Once the basic concepts are absorbed,their extensions to more general cases is typically routine and several such extensions (but not an exhaustive list) are discussed.

信道编码威廉·瑞安,林舒 著The title ofthis book, Channel Codes: Classical and Modern,was selected to reflect the fact that this book does indeed cover both classical and modern channel codes,It includes BCH codes, Reed-Solomon codes, convolutional codes, finite-geometry codes, turbo codes, low-density parity-check (LDPC) codes, and product codes.However, the title has a second interpretation. While the majority of this book is on LDPC codes, these can rightly be considered to be both classical (having been first discovered in 1961) and modern (having been rediscovered circa 1996). This is exemplified by David Forney's statement at his August 1999 IMA talk on codes on graphs,lt feels like the early days. As another example of the classical/modern duality, finite-geometry codes were studied in the 1960s and thus are classical codes. However, they were rediscovered by Shu Lin et a/. circa 2000 as a class of LDPC codes with very appealing features and are thus modern codes as well. The classical and modern incarnations of flnite-geometry codes are distinguished by their decoders: one-step hard-decision decoding (classical) versus iterative soft-decision decoding (modern).
