Training Sequence Design For Burst Mode Single Side Band CPM Synchronization
Résumé
This paper studies the Cramér-Rao bound (CRB) for burst-mode transmission synchronization of Single-Sideband Frequency Shift Keying (SSB-FSK). Based on the CRB computations of burst-mode CPM, for conventional double sided schemes, it was shown that it is possible to obtain an optimum training sequence that minimizes the CRBs simultaneously for the joint estimation of symbol timing, frequency offset, and carrier phase. However, due to the SSB-FSK non-antipodal alphabet, it is impossible to use the same optimum sequence to minimize the CRBs for all parameters simultaneously. Meanwhile, in this paper, we propose a new general training sequence that can minimize the sum of all CRBs for any binary SSB-FSK. The derived results can be helpful for data-aided (DA) synchronization of SSB-FSK modulation.
