Common frame synchronization schemes are:

Framing bit
A common practice in telecommunications, for example in T-carrier, is to insert, in a dedicated time slot within the frame, a noninformation bit or framing bit that is used for synchronization of the incoming data with the receiver. In a bit stream, framing bits indicate the beginning or end of a frame. They occur at specified positions in the frame, do not carry information, and are usually repetitive.
Syncword framing
Some systems use a special syncword at the beginning of every frame.
CRC-based framing
Some telecommunications hardware uses CRC-based framing.
