    摘要： Embodiments of the present invention disclose a coding method, a wireless device, and a chip. The coding method includes: obtaining, based on a sequence whose length is 2 n' , a mother code sequence used for coding, where the sequence whose length is 2 n' includes 2 n' sequence numbers, a length of the mother code sequence is 2 n , the mother code sequence includes 2 n sequence numbers, the 2 n sequence numbers are some or all of the 2 n' sequence numbers, n' is a natural number, and n is a natural number less than or equal to n'; and coding an input to-be-coded bit by using the mother code sequence. According to this method, a system may store only one or more long sequences, and then obtain a required mother code sequence from one of the long sequences according to a coding requirement, thereby reducing storage overheads of the system.

    摘要： Embodiments of this application disclose a GEL codeword structure encoding method. The method in the embodiments of this application includes: first transforming an H C of a code B into an H B ; obtaining a parity bit of the code B by performing an operation on the H B and an information bit of the code B; using the parity bit of the code B as an information bit of a code A to perform RS coding on the code A, to obtain a parity bit of the code A; then obtaining a check code of a GEL code by performing an operation on the parity bit of the code B and the parity bit of the code A; and finally adding a single bit parity check SPC parity bit, where the code A is defined in a finite field GF (2 l1 ), the code B is defined in a finite field GF (2 l2 ), and l 1 and l 2 are positive integers. In this way, the SPC parity bit can be used as prior information of a code A in a first row, so that a success rate of decoding the code A in the first row is improved. In addition, in a GEL codeword structure design process, l 2 may be reduced as much as possible, that is, a bit width of a code B symbol is reduced, and complexity of decoding the code B is reduced, so that codeword overheads are reduced, and performance of the GEL code is effectively improved.
