US 11,239,946 B2 · Data encoding method and device, storage medium, and processor

Abstract

Provided are a data encoding method and device, a storage medium, and a processor. The method includes: obtaining data to be sent; performing quasi-cyclic low-density parity check (LDPC) encoding on the data to be sent to obtain an LDPC codeword sequence, and interleaving the LDPC codeword sequence to obtain an interleaved LDPC codeword sequence; performing cyclic bit selection on the interleaved LDPC codeword sequence from a starting position to obtain a rate-matched codeword sequence, where the starting position is determined according to a predetermined parameter; and sending the rate-matched codeword sequence. The solution above resolves the problem in the related art of unstable transmission after performing quasi-cyclic LDPC encoding on data to be transmitted, and achieves stable transmission after the quasi-cyclic LDPC encoding.
