On the Influence of Pilot Symbol and Data Symbol Positioning on Turbo Synchronization

When realizing carrier frequency offset estimation at low signal-to-noise ratios, a typical feed-forward synchronization unit solely relies on known pilot symbols. The importance of the position of these pilot symbols within the burst has been elaborated on in the literature. In this paper, we discu...

Summary:When realizing carrier frequency offset estimation at low signal-to-noise ratios, a typical feed-forward synchronization unit solely relies on known pilot symbols. The importance of the position of these pilot symbols within the burst has been elaborated on in the literature. In this paper, we discuss the importance of the pilot symbol constellation for iterative code-aided synchronization. Furthermore, we investigate the transmission order of data symbols for a turbo coded system with code-aided synchronization.
