Abstract: This application provides example concatenated code encoding and decoding methods. In one example method, polar code encoding is performed on a to-be-encoded message bit sequence based on a frozen bit set and a message bit set that are of a first polar code, to obtain a first encoded code word whose length is N_o. The first encoded code word is interleaved to obtain a second encoded code word, and optimized low-density parity-check (LDPC) code encoding is performed on the second encoded code word to obtain a concatenated code word. Interleaving includes both outer interleaving and inner interleaving. The concatenated code word is then outputted.
