Hi all,

I am new to demodulation and FEC.

How can I get each bit's soft-probability from the constellation?
For example, the modulation method is 16QAM, How can I get P(bit1=0),P(bit2=0),P(bit3=0),P(bit4=0) from a symbol?

Is it belong to the subject of detection and need viterbi algorithm?

Or can you recommend some key words of this subject?

Best regards,
Davy
