Burrows Wheeler Transformation (BWT) (Burrows and Wheeler,1994) compression system has been known for its good compression efficiency for text files.Files transformed by the BWT are usually modified by a Move To Front (MTF) transformation.A MTF text is piid (piewe-wise independent data), and the coder needs to adaptively readjust the coding statistics to fit the features of tehe running segment.The common way to do this is to rescale coding statics after a certain amount of coding steps.This paper describes an alternative, which "virtuallly" adjusts the statistics in each coding step, and the results are presented.
