Compression means making things smaller by applying pressure. Text compression is not about physically squashing text, but about finding ways to represent t in fewer bits or bytes. It is necessary that the coded form can be decompressed to reconstitute the original text ( otherwise, compression is trivial!), and it is usually important that the original is recreated exactly, not approximately.

This book explains a new generation of language-independent universal compression methods from the conceptual to the implementation level, including full details of algorithms and comprehensive performance comparisons. For courses in communication algorithms or data communications.
