Abstract

A recent development in data compression area is Burrows-Wheeler Compression algorithm (BWCA). Introduced by Burrows and Wheeler, the BWCA achieves compression ratio closer to the best compression techniques, such as partial pattern matching (PPM) techniques, but with a faster execution speed. In this paper, we analyze the combinatorial properties of the Burrows-Wheeler transformation (BWT), which is a block-sorting transformation and an essential part of the BWCA, introduce a new transformation, and delineate the new transformation with the BWT based on the multiset permutations.
1 * Some sections of this work have been presented at two different meetings of the IEEE Data Compression Conference, DCC-1998 and DCC-2002.
Keywords: Block-sorting; BWT transformation; Multiset permutations; Lossless compression
