Abstract
A method for supporting a receiving operation based on 2D-NUC performed by a first wireless device according to the present embodiment, comprises the steps of: receiving first and second input information from a second wireless device; performing equalization on the first and second input information; and generating LLR information on the basis of lookup table information predetermined for the equalized first and second input information and 2D-NUC.
Claims13
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 STA, 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.
A wireless device for supporting a reception operation based on a 2-dimensional non-uniform constellation (2D-NUC), the wireless device comprising:
- an equalizer to generate equalized first input information and equalized second input information by equalizing first input information and second input information;
- a first NUC demapper to generate a first log likelihood ratio (LLR) set based on the equalized first input information and predetermined lookup table information for the 2D-NUC;
- a second NUC demapper to generate a second LLR set based on the equalized second input information and the lookup table information;
- and
- a low-density parity-check (LDPC) decoder to receive LLR information generated based on the first LLR set and the second LLR set.
