Abstract
Embodiments of polar encoding/decoding methods and apparatuses are described. CRC encoding is performed on an information block to obtain a CRC encoded block with a length of B, where a CRC length is Lcrc, an information block length is K, and B=K+Lcrc. The CRC encoded block is interleaved. Lpc CRC bits in the interleaved encoded block are located between bits of the information block. Each CRC bit of the Lpc CRC bits is located after all bits checked by using the CRC bit. Lpc is an integer greater than 0 and less than Lcrc. The interleaved encoded block is mapped to information bits. A frozen bit is set to an agreed fixed value. Polar encoding is performed on the information bits and the frozen bit to obtain a polar encoded codeword to improve performance of a CA-polar code.
