Hi Tongyang
In BCJR decoder we exclude the intrinsic information and pass the aposteriori probability from one decoder to another for subsequent detection

yes

Hi Filip
I don't think there is any problem in scaling. Why would you divide the SNR in all 3 bits?

Hi Yogesh,

As from your code, the information you exchanged between two decoders is the a-posteriori information not extrinsic information as in theory. Is there any difference in the performance ? If I want to use extrinsic information in this case, how I can ? Thanks.

from your PDF report, you mentioned that only extrinsic information is exchanged between two BCJR decoders. However, in your MATLAB code, I think the exchanged information is the a-posteriori information. Is it correct? Thanks.

hi.. is the used interleaver a random permutation interleaver?
