Abstract: The disclosure proposes a technique for achieving validity decision performance of a suitable level in communication and broadcasting systems using a polar code. The polar code is a channel code in which it is difficult to use a syndrome check due to a successive cancellation (SC)-based decoding operation and coding structure. Accordingly, in the communication of the related art and broadcasting systems using the polar code, a validity check of a decoding result has been performed by using a path-metric (PM) generated during decoding and a concatenated error detection code, such as a cyclic redundancy check (CRC) code. However, it is difficult to achieve target error detection performance only via such methods when the length of the CRC code is short or when input and output lengths of a code are short.
