How to get an output of viterbi decoding IP?

Question

Hi all

I am using viterbi decoding to establish an OFDM system, while I can not get the output

I'm using parallel implementation with continuous optimization

traceback= 42 soft bits = 1 N = 2 L = 7 GA = 133 GB = 171

The output signal "source_val" "decbit" still force low, while I can get the result if I choose the block optimization with all other things same.

Please help me why it doesn't work~~

Thanks
