Physical layer is only concerned with the transmission of a sequence of bits from one point to another. Suppose that the sequence 110010011 is used as a synchronization sequence preamble to a data packet. Propose a method that can be used to allow the channel to distinguish the synchronization sequence from an identical data sequence within the packet. In what layer of the TCP/IP model would you implement your solution?
