Abstract

A binary code has bounded synchronization delay if there exists an integer \(s\) such that at most \(s\) consecutive bits are required to establish word synchronization in any message. The code whose words are lexicographically least in the non-periodic orbits determined by cyclic permutation of all words of length \(n\) is called the canonical bounded synchronization delay code. It has the maximal number of words possible in a synchronizable code of fixed word length. Any code of fixed word length \(n\) can be represented as a set of vertices in the \(n\)-cube. We prove that the canonical bounded synchronization delay code is a connected subset of the \(n\)-cube.
