Forward Error Correction

A–7

decoder synchronization state can be used to verify the correct lock point has been achieved, and to reject
the false locks.

However, if uncoded operation is used, there is no way to recognize a data false lock. The demodulator
will indicate that it is correctly locked, but the data out will not be correct.
