I am not sure if this is the right place to ask, but I am stuck already a couple of days.
I have implemented a soft Hamming decoder (LLRs) in MATLAB and now I have to create a soft-output for this decoder.
My attempts all failed, since the soft-outputs do not match the hard-bits.

The paper I am using as reference is: LINK
There is a very clear explanation in it, with straightforward steps.
However, for some reason the outputs are calculated incorrectly.
I am wondering if it is perhaps due to the large LLR values I am putting into the decoder?

Could somebody help me to figure this out?
