Abstract: A polar code-based decoding method may comprise: converting a plurality of LLRs of calculation-target bits into a plurality of absolute (ABS) LLR values; sorting the plurality of ABS LLR values in order of size so that a minimum ABS LLR value is designated from among the plurality of ABS LLR values; multiplying the minimum ABS LLR value by a preset weight; and updating path metrics (PMs) of the calculation-target bits in an order in which the plurality of ABS LLR values are sorted, wherein the updating of the PMs of the calculation-target bits comprises, even when a specific ABS LLR value of a specific calculation-target bit is equal or similar to the minimum ABS LLR value, updating a PM of the specific calculation-target bit with the minimum ABS LLR value multiplied by the preset weight.
