    摘要： Embodiments of the present invention provide an encoding/decoding method, apparatus, and system, and relate to the communications field. The present invention may improve decoding performance and improve accuracy of a survivor path. The method includes: encoding information bits according to a first-level encoding method to obtain a first-level encoded code word, obtaining a sorting value of each check bit of the first-level encoded code word, and adjusting each check bit to a corresponding position according to the sorting value of each check bit, where the sorting value refers to a value of S when the check bit is related to first S information bits of the information bits in the first-level encoded code word, and S is a non-zero integer; and performing, according to a second-level encoding method, second-level encoding on the first-level encoded code word after positions of the check bits are adjusted, thereby obtaining a second-level encoded code word. The present invention is applicable to various communication systems.

    摘要： According to embodiments of the present disclosure, a method and a chip for cyclic code encoding, a circuit component, and an electronic device are provided. A first cyclic code includes K payload symbols and (N-K) parity symbols, and each symbol includes m bits, where K, N, and m are integers greater than or equal to 1, and N is greater than K. The method includes: generating, based on a first symbol sequence related to a first part of symbols in the K payload symbols, a first parity sequence corresponding to the first symbol sequence. The method further includes: generating, based on a second symbol sequence related to a second part of symbols in the K payload symbols, a second parity sequence corresponding to the second symbol sequence, where the first part of symbols are different from the second part of symbols. The method further includes: generating the (N-K) parity symbols based on the first parity sequence and the second parity sequence. In this way, a small bit width cyclic code encoder may be used to implement large bit width cyclic code encoding.
