Abstract: A device for decoding input data including first candidate data and second candidate data by using a polar code, the device includes a first path metric processor configured to generate first candidate path metrics based on a first parent path metric by decoding the first candidate data, determine at least one first child path metric among the first candidate path metrics based on first reliability values of the first candidate path metrics; and a second path metric processor configured to generate second candidate path metrics based on a second parent path metric by decoding the second candidate data, and determine at least one second child path metric among the second candidate path metrics based on second reliability values of the second candidate path metrics, a quantity of the at least one first child path metric being different from a quantity of the at least one second child path metric.

Abstract: A method of encoding input data as a polar code includes generating unfrozen bits by adding at least one designated information bit to information bits which have been generated based on the input data, reordering the unfrozen bits and frozen bits by assigning the unfrozen bits to polarized sub-channels having higher reliability than the frozen bits having a value known to both of an encoder and a decoder, and generating a code word by polar-coding results of the reordering may be provided. The at least one designated information bit may have the value known to both the encoder and the decoder.
