Patent ID: 8300571

Claim:
A terminal to identify a start of frame location for a received wireless signal, the terminal comprising: a receiver module configured to receive a wireless signal transmitted via a satellite; an A/D module, communicatively coupled with the receiver module, and configured to process the received wireless signal to generate a digitized stream of symbols comprising a physical layer signal; and a correlator module, communicatively coupled with the A/D module, and configured to: calculate a plurality of correlation values over a period for the digitized stream, each of the correlation values comprising a correlation between different portions of the digitized stream of symbols, wherein the different portions of the digitized stream comprise a plurality of code blocks; wherein each code block comprises a first half and a second half; and wherein the first half of the code block is substantially symmetrical to the second half of the code block; and utilize the plurality of correlation values by correlating the first half and the second half of each code block to locate one or more correlation peaks for identifying the start of frame location.
