A Fast Test for Unique Decipherability Based on Suffix Trees
Abstract
The classical algorithm for testing unique decipherability of codes is improved by using McCreight’s algorithm for constructing suffix trees. The complexity of the algorithm is O(nm) where n is the number of codewords and m is their total length. Efficiency is gained by avoiding repeatedly comparing subwords of the codewords. © 1982. IEEE.
