Applications of Data Compression Techniques to a Communication System

摘要

A brief overview of current status of data compression technologies are presentedwith the interim development of compression software and tests of effectiveness on the selected digitized data types. Several algorithms such as Rice, LZ-family, and run-length codings are examined for selected digitized packet data streams. These algorithms are able to compress most data available with a fairly good compression factor except for Tape A and encrypted data. Tape A data contains a mixture of several data formats in very short runs (several packets), rather than the long runs (typically hundreds of packets), for which the current version of the software was designed. The remaining data sets were compressed with a compression factor of over 2.74.
