Hi all,

I am working on an iterative SOVA decoder for Turbo, I want to know the general idea of iterative decoding, do we use the reliability bits output from the first decoder as the reliability bits to be updated in the second decoder? I want to know what are the soft bits that are produced prior to the hard limiter?

Thanks.
