Using arithmetic code to improveperformance of Lempel-Ziv encoders
Marcelo S. Pinho, Weiler A. Finamore · Electronics Letters · 2000
Recently it was shown that the Lempel-Ziv'78, an encoder which has motivated many practical data compressors, does not have optimal redundancy for many classes of sources. The authors present work which shows that this redundancy can be significantly improved by use of an arithmetic code. Practical benefits obtained from this technique are also presented.
