A method for supporting a reception operation based on a 2-dimensional non-uniform constellation (2D-NUC), the method comprising:
- receiving, by a first wireless device, first input information and second input information from a second wireless device;
- equalizing, by the first wireless device, the first input information and the second input information;
- and
- generating, by the first wireless device, log likelihood ratio (LLR) information based on the equalized first input information, the equalized second input information, and predetermined lookup table information for the 2D-NUC,
- wherein the equalized first input information is configured based on a first inphase (I) value and a first quadrature (Q) value,
- wherein the equalized second input information is configured based on a second I value and a second Q value,
- wherein first LLR information in the LLR information is determined based on a first LLR set, a sign of the first I value, and a sign of the first Q value, and
- wherein the first LLR set is determined based on the equalized first input information and the lookup table information.
A first wireless device for supporting a reception operation based on a 2-dimensional non-uniform constellation (2D-NUC), the wireless device comprising:
- a memory;
- a transceiver;
- and
- a processor operatively coupled to the memory and the transceiver,
- wherein processor is configured to:
- receive first input information and second input information from a second wireless device;
- equalize the first input information and the second input information;
- and
- generate log likelihood ratio (LLR) information based on the equalized first input information, the equalized second input information, and predetermined lookup table information for the 2D-NUC,
- wherein the equalized first input information is configured based on a first inphase (I) value and a first quadrature (Q) value,
- wherein the equalized second input information is configured based on a second I value and a second Q value,
- wherein first LLR information in the LLR information is determined based on a first LLR set, a sign of the first I value, and a sign of the first Q value, and
- wherein the first LLR set is determined based on the equalized first input information and the lookup table information.
