Irreducible Cyclic Codes and Polyadic Codes $135.42 PMIn this book, explicit expressions of all thegenerating idempotents of irreducible cyclic codes oflength p n and 2p n over GF(q) are obtained, where pis an oddprime, p does not divide (q f1)/p if n gt; 1 and f isthe multiplicative order of q modulo p. Also thegenerating idempotents of all theirreducible cyclic codes of length 2 n over GF(q),where q is any odd prime power, are determined.It is also proved that the generating idempotents ofirreducible cyclic codes can be effectivelyevaluated, once they are known for irreducible cycliccodes of length prime power length. The weightdistributions of all the irreducible cyclic codes oflength 2 n are also obtained directly from theirgenerating polynomials. The necessary and sufficientconditions for the existence of cyclic polyadic codesof prime powerlength and of arbitrary length are obtained. The results on the existence of polyadiccodes, obtained by us, will enable one to constructpolyadic codes of varying lengths and dimensions.Many interesting examples of good codes arise fromthe family of polyadic code Author: Sharma, Anuradha Binding Type: Paperback Number of Pages: 132 Publication Date: 2011/06/14 Language: English Dimensions: 9.02 x 5.98 x 0.31 inches |

Covering Codes $300.18 The problems of constructing covering codes and of estimating their parameters are the main concern of this book. It provides a unified account of the most recent theory of covering codes and shows how a number of mathematical and engineering issues are related to covering problems.Scientists involved in discrete mathematics, combinatorics, computer science, information theory, geometry, algebra or number theory will find the book of particular significance. It is designed both as an introductory textbook for the beginner and as a reference book for the expert mathematician and engineer.A number of unsolved problems suitable for research projects are also discussed.

Designs and Their Codes $258.09 Algebraic coding theory has in recent years been increasingly applied to the study of combinatorial designs. This book gives an account of many of those applications together with a thorough general introduction to both design theory and coding theory developing the relationship between the two areas. The first half of the book contains background material in design theory, including symmetric designs and designs from affine and projective geometry, and in coding theory, coverage of most of the important classes of linear codes. In particular, the authors provide a new treatment of the ReedMuller and generalized ReedMuller codes. The last three chapters treat the applications of coding theory to some important classes of designs, namely finite planes, Hadamard designs and Steiner systems, in particular the Witt systems.

AlgebraicGeometric Codes $96.59 Security of data by means of cryptography is becoming more and more important in many areas of our lives. Publickey cryptosystems (PKC) form an important part of cryptography as they allow convenient and secure communication between all users. The objective is to develop PKCs that provide a high level of security while being fast and easy to use. The author Robert Niebuhr analyses the application of AlgebraicGeometric Codes (AGC) in Cryptographic Systems. Starting with a brief discussion of Algebraic Geometry and the general construction of PKCs, he shows how to use AGC including encoding, decoding and errorcorrection. To demonstrate the concrete application he develops a Cryptosystem using the McEliece Scheme and evaluates its properties. This book is a useful reference for students, professors, and everybody with some mathematical background and an interest in cryptography.
