  • Patent number: 5003535
    Abstract: Packet synchronization is obtained by employing a unique packet transport word including at least one prescribed parity check pattern in conjunction with a packet length indicator. An at least one prescribed parity check is computed over transport word length blocks of bits of an incoming packet and compared to an expected parity check pattern in predetermined bit positions in the incoming block of bits to identify possible transport word candidates. Once a transport word candidate is identified the packet length indicator is used to point to the next transport word candidate. Synchronization is declared upon obtaining a parity match for a subsequent transport word candidate pointed to by the packet length indicator. In a specific embodiment, at least two prescribed parity checks are employed to denote a possible transport word candidate.
