[srsran-users] Regarding calculation of LLR

[waseem bhat]

Hello Community members,

I have a query on LLR calculation during symbol demodulation. I am trying to understand LLR values corresponding to each symbol.
So i added a print using _mm_cvtsi128_si32() in function demod_16qam_lte_s_sse()
https://github.com/srsran/srsRAN/blob/master/lib/src/phy/modem/demod_soft.c

However the LLR print values are coming wrong. I am not sure, how can i print the LLR values corresponding to each symbol in the mentioned function.

I am trying this to understand the mechanism & corresponding code. Any inputs will be very help.
I hope this is a right forum to ask this particular question.

//Thanks & Regards,
Waseem Bhat
