The V.42bis standard for data-compressing modems
- Univ. of Minnesota, Duluth, MN (United States)
The recently adopted CCITT V.42bis standard for data-compressing modems is a conservative and economically implementable scheme, one discussed here from algorithmic, experimental, practical, and marketing standpoints. V.42bis compresses text about as well s the Lempel-Ziv-Welch algorithm of the Berkeley Unix Compress utility; other Ziv-Lempel variants are discussed briefly. Even though better compression ratios can be obtained with these variants, V.42bis is eminently suitable for implementation on a contemporary modem. 11 refs., 5 tabs.
