Hello everyone,

I am currently busy in implementing DAB Receiver on a DSProcessor where I am facing a hurdle.

The code works fine with protection level 1, but fails for other protection levels. I am currently using hard decision for Viterbi. Will it help if I use soft decision? If yes how and at what stage of my decoder do I generate the soft decision bits?

I would be thankful to anyone who is ready to help me in this regard.
