Abstract

We present an algorithm to sort all suffixes of $x^n=(x_1,\dots,x_n) \in {\cal X}^n$ lexicographically, where ${\cal X}=\{0,\dots,q-1\}$. Fast and efficient sorting of a large amount of data according to its suffix structure (suffix-sorting) is a useful technology in many fields of application, front-most in the field of Data Compression where it is used e.g. for the Burrows and Wheeler Transformation (BWT for short), a block-sorting transformation ([3],[9]).
