Data sequences which are encountered in many situations of digital communications and data processing and are not specified as sequences from certain sources, usually display various structural regularities and allow for storage and time-saving techniques of data compression by using the regularities.<BR>In this paper, a scheme of sequential data compression is presented. its performance is investigated and proved to be asymptotically optimal for mernoryless sources. The compression algorithm is used in another compression scheme, whose performance is also investigated and shown to be asymptotically optimal for first-order Markov sources. A simulation study is carried out for the illustration of algorithm developed here.
