CTH11-6: Performance Analysis of Frame Synchronization for Non-Uniformly Distributed Data Symbols

Frame synchronization is classically treated in literature for equiprobable data symbols. In this case the optimum metric has been derived both in the case of periodically and aperiodically embedded synchronization words and the corresponding performance has been evaluated. In this paper we evaluate the performance of sequential frame synchronization for non- equiprobable data symbols, assuming no a-priori information about data distribution. Results show that the performance may sensibly differ from the case of equiprobable data symbols and strongly depends on the chosen synchronization word.
