[Click the star to watch this topic] frame sync problem degrading FEC performance

Hello all,
I am developing a FEC system in our custom modem based on tms320vc5416.
I am facing a problem in it. Since FEC works on block of data to detect
& correct errors, frame synchronisation is must. But if frame header
gets corrupted then entire FEC block following header will be discarded
and it will result in loss of data or errors. What can be done to
ensure there is frame sync but no loss of data even if header is
corrupt. I know this sounds funny, but because of this problem, our
systems with or without FEC are giving almost same performance. I need
help on this urgently. Thanks. bye...
