Abstract

The first challenging step of the demodulation of the Digital Video Broadcasting Second generation signal is frame synchronization. Physical Layer header is composed of Start of Frame and Physical Layer Signalling code. When the Start of Frame and the structure of Physical Layer Signalling code are known, Choi and Lee, Kim et al denote some Choi Lee Detectors and Post Detection Integration techniques, using the combination of differential detection of header code. In this paper, we present a scheme to achieve frame synchronization on the condition that the Physical Layer header code is uncertain.
