Hi Long
I have not checked if there is any difference in the performance if we use extrinsic information.
If you want to use extrinsic information, just substract the intrinsic term given on page 4 of
http://home.iitk.ac.in/~ysoniwal/Term_Paper_Reports/EE624.pdf
from aposteriori information.

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,

your code is very well!! But there is a thing that I don't understand and it is: I don't understand as you encode P1 and P0. I have readed the description in page 2 and 3 of your paper, but I don't understand, Could you explain me it? And as you implements it in the code?

Thanks you.

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.
