ABSTRACT:
A system and method for obtaining and maintaining synchronization with an incoming signal prior to and during the transmission of data. Specifically, embodiments of the present invention contemplate that synchronization is obtained by searching for an initial portion of a pattern in an input signal. Once the pattern is detected, the pattern (and/or some mathematical derivation thereof) must subsequently be detected a pre-determined number of times. Once synchronization has been obtained, a pattern is continually looked for in the input signal in order to maintain synchronization. The present invention maintains this synchronization even though data may be embedded within this input signal.
