This paper proposes a novel frame synchronization scheme for convolutionally encoded data packets. Rather than placing sync bits in a separate header, the sync bits are placed in a mid-amble and encoded as part of the data sequence, using the error correction encoder to resolve time ambiguities. This technique requires fewer bits for frame synchronisation. The performance improvement over conventional synchronization techniques is explored via simulation. The applicability of the scheme for synchronization of turbo codes is also discussed.
