A system for receiving and handling a scrambled input data signal that includes a preamble with a start of frame delimiter (SFD) initiates an SFD search on the scrambled input data, thereby attempting to save an initialization period. The initialization period may be of the order of 7 uS, and its saving results in improved timeline management enabling antenna diversity and the possible use of high performance algorithms. The system may use two parallel paths for signal processing, each having an SFD detector and a descrambler. If the detected SFD is short, then the second path is disabled, and if it is long, then the first parallel path is disabled. Alternatively, the first path can be used for a finite period of time (for e.g., 40 symbols) and if the SFD is still not detected, the first path is disabled, and the system uses only the second path.
