The Theory of Error-Correcting Codes (Volume 16) (North-Holland Mathematical Library, Volume 16)

A classical reference in coding theory

excellent

Very good

I find it a shame that I can't give this book five stars as it has been one of the definitive works of error correcting codes for over 25 years, but the Index is just really bad. One of the major types of symmetry is the self-similar Hadamard matrix and it isn't in the Index.This book has some of the most difficult mathematics known in it,and does an even better job of telling about it than the similar chapters in Sphere Packings, Lattices and Groups (Grundlehren der mathematischen Wissenschaften) (v. 290)  :"Sphere Packings".That a field of combinatorial arguments ( Golay, Leech, Mathieu, Hadamard, Paley) should be as effective as thisin coding as well as the geometry of groups is very remarkable.
