Abstract
Methods and systems for determining a Log-Likelihood Ratio (LLR) corresponding to each bit of a symbol are provided. The symbol comprises a predefined number of bits based on a predetermined constellation. The methods and systems include expanding the predetermined constellation. The predetermined constellation comprises a plurality of constellation-points wherein each constellation-point has a unique X co-ordinate and Y co-ordinate. Also, the expanded predetermined constellation further comprises points corresponding to each combination of the X co-ordinate and the Y co-ordinate of the constellation-points. The methods and systems further include calculating the LLR corresponding to each bit of the symbol based on the expanded predetermined constellation.
